I think this is a red herring. Politicians like to think they can use the latest technology to connect with the people, but all they want to do is use it for propaganda and to curtail our privacy. There are very few politicians who use either the internet or social media to any effect. Caroline Lucas and the Green Party do it very well. The lunatic fringe of UKIP and the Tories just use it to spread hate and fear. Labour constantly use it to make announcements but don't care what even their own voters have to say by way of comment. Politicians don't have to use these channels to be effective, for instance Glenda Jackson is a true conviction politician I admire but I never hear about her Twitter account, whereas I do see her Commons performances circulated on social media by others. It's the content that's important, not the medium.
