Â鶹Éç

In 2010 the awful term "sofalising" was coined. It is communicating with friends online while lounging on the sofa rather than going out.

Now we are seeing another interesting online phenomenon - people sitting at home watching a programme on TV while at the same time discussing what they are watching on another screen with friends, or indeed strangers, on social media sites.

There is .

This is really interesting territory for Newsnight, or #newsnight as we are known on Twitter. As our viewers pick up on, share and spread the debates introduced on the programme on Twitter, our hashtag can enter the UK trending lists.

This week's was just the latest example. Bennett reiterated his previously expressed belief that closing libraries constitutes child abuse - his views were then picked up on Twitter, resulting in his name appearing among the most cited phrases in the UK on the social media site after the programme.

This dual-screen media phenomenon is being driven by rapid changes in technology consumption. There has been 40% growth in mobile web use over the last 12 months, on smart phones especially, and all media organisations are predicting it will be a key growth area.

Good TV, especially for an organisation like the Â鶹Éç, is often about being a space for collective audience experiences where communities can coalesce. And that's why our regular TV audience sat at home watching us on telly while tweeting about us from their laptops or mobiles is so important.

There has even been speculation that we sit in the programme gallery monitoring what is being said on social media and end interviews if someone is not going down well. For the record, we do not. Some nights we might find ourselves having no-one left to interview if we did.

There is an important caveat. Newsnight's social media audience is still a fraction of its television audience, and a fraction of the audience who consume our online content.

The numbers are still dwarfed by viewers who never mind tweeting from their smart phones, might have no internet access at all. So we need to be careful what we take from it but as raw data on what our audiences really think and react to immediately it is really useful.

The Â鶹Éç is looking into how it can use second screens to complement what is happening on the dominant screen and how it can broaden the discovery, appeal and engagement with its audience by doing so. So watch this space... or should I say both spaces.

For anyone who's been wondering when we are bringing out an Android version of the Â鶹Éç News mobile app, I'm very pleased to say it will be available from today - initially in the UK, then internationally soon after that. My colleague in Â鶹Éç Future Media Anthony Sullivan has posted more details here.

Steve Herrmann is editor of the Â鶹Éç News website.

Ten years ago this week, an understated revolution started at the Â鶹Éç News website. It was then, with a general election campaign under way, that Nick Robinson started writing a column on the site. Nick was then in a role which meant he kept popping up on Â鶹Éç News 24 once or twice an hour to report and explain the twists and turns of the day in Westminster. His new online column was designed to be a bit like that - snippets of information, bits of analysis, even possibly inconsequential observations. It took a bit of a leap of faith on Nick's part to agree to take part, not least because it was extra work for no extra reward, but also because the internet was much more of a minority sport in those days. Fortunately I managed to persuade him that it was worth a go.

The idea became , and looking back at those pages today makes me feel that it actually stands up pretty well. We didn't know if this new format, which was loosely based on the pioneering blogs of the time, would be a diary column, or breaking news, or end-of-day analysis or running commentary - or all of them. But it went down well and later in 2001 Nick Robinson's Newslog was born.

The role blogging has played in news coverage over the past 10 years has been much talked about - we know of at least one thesis which is being written on how we do it here at the Â鶹Éç - but it's hard to imagine our website without the voices of our Pestons, Flanders, Mardells, Eastons, and yes, Robinsons, with many more besides. The contribution of analysis and explanation the experts of Â鶹Éç News now make to the site is undoubtedly one of our major strengths. The reason for mentioning this now is that, as we promised earlier this year, this week we are completing what we see as a pretty fundamental reinvention of how our blogs operate.

For some time we've been frustrated that the contributions of our key editors feel like they are tucked away on the site - more number 13 court than Centre Court - and so one thing we decided to do was to start producing their blogs in our main production system. For the past six years they have been created in Movable Type, a specialist blog software, which is why the pages look different to our news pages. This shift promises us extra efficiency and flexibility, and we hope that it will make our top correspondents' analysis feel much more like an integral part of the website.

There will, of course, be some changes. The design and navigation are very different. The text will look more like normal news stories or features. But the content will be the same. Nick & co will still each have their own page, and these will still operate like blog indexes, with the newest entry at the top. You can see how it looks with Mark Mardell's page here which has already moved over to the new design. And part of the plan is to make these new pages the place where you can follow a particular correspondent, whatever form of journalism they are producing. So we plan over the next few weeks to incorporate correspondents' tweets, if they have them, into their pages, along with some of their reports in audio and video, and also where they add "text box" contributions to news stories (see right). We hope that, together, these will make a compelling and new way to follow a story or subject.

There are also changes to the way comments will work, as a result of the introduction of comments on stories across the wider site (social media editor Alex Gubbay explained some of the changes here). With some news stories each day having comments on them, there may be times when a story and correspondent's analysis cover the same subject. To avoid unnecessary duplication and even confusion, generally we will seek to have comments on one or the other. So correspondents' pieces may not always include comments. In addition, in our new system, comments have a maximum length of 400 characters. It's my view that this makes for sharper contributions, though I know some disagree. As with all new developments on the site, however, it's something we watch closely to see if it's working.

Perhaps though the biggest advantage of the changes I've outlined is that it will be much easier for us to include our correspondents' articles wherever people access Â鶹Éç News - mobile phones, for example, and also in apps. And - we hope - also on devices which will have been invented by the time another 10 years rolls around.

Update, 12:19, 12 May: Thanks for your comments so far. We're working through putting all the new pages live at the moment, but we are taking note of what you are saying - particularly so far about the changes to comments, RSS and the character of blogs. I'll be putting together some responses and will post them here.

Update, 17:50, 13 May: Thank you again for your comments, both on this post and on several of our bloggers' new pages.Ìý The issue of comment length is clearly one that exercises many of you. In my original post I said I thought a character limit made for sharper comments, and I do believe that, but I also want to emphasise that it's certainly not our intention to encourage people to dumb down their contributions, as some of you fear. Others say that the changes will make debate harder. As Jan Keeskop says, my colleague Alex Gubbay did spell out our thinking about comments when he said that "this process is essentially about us online focusing more now on encouraging discussion around our content itself, rather than looking to host or manage a community". We are trying to maximise the editorial value of contributions but we do not have unlimited resources to do this. Since it's less efficient to moderate longer comments than shorter ones, length is one of the factors we are taking into account. Making these changes is not an exact science. It is something we are keeping under review, though, so please don't think that your complaints have gone unnoticed.

Changes to the RSS feeds are something I should have mentioned earlier, and I apologise for not doing so. Whereas we previously offered full text feeds of blogs, the RSS feed of the new pages is headline and summary only. I recognise that this is clearly an issue for lots of people, and is frustrating to those who have been using our feeds. The change is an unintended consequence of moving into our main production system, which does not automatically export full text feeds. We are looking at the issue and I hope to be able to come back to you with more detail.

Thank you to those who have made points about how the new page format works - the feedback is useful. We're trying to do something new with these pages, preserving the best of the blog environment while recognising that there is lots more going on with our key journalists than just their blogs. There are also more places that we want their content to reach - more platforms and more devices - and that is one of our reasons for making these changes. There will be more functionality rolling out in the next few weeks, with tweets, videos, and analysis text boxes on news stories being included; development of these pages is by no means finished. It has, however, been cheering to notice examples already where the new format seems to be working effectively, for example Mark Mardell's post here or Jonathan Amos’s post here. Ìý

Update, 08:40, 17 June: Thanks again for your comments, and my apologies for not getting back sooner. One of the points made by several commenters was that, aside from comment length, the layout of comments on our new blogs did not encourage discussion since it showed comments with most recent first. It was therefore difficult for people to follow the debate from the beginning. I'm happy to report that since the start of this week, comments on our new blogs are now shown with the oldest comment first, meaning it should now be much easier for discussion to take place.
