Tonight on BBC TV it's Newsnight's turn to interview the co-founder of Twitter, a chap called Evan Williams, aka @Ev. At 10:30 he'll be on, and if you have a question for him, go on to Twitter and ask (you have to address the question to @bbcnewsnight).
This is the first mainstream TV interview I've known Ev to do, as he leaves most of the PR work to his colleague Biz Stone, aka @biz. I'm really looking forward to it, as Ev's got an interesting story that I hope he gets a chance to talk about.
Before founding Twitter, Ev was one of the principal figures behind the growth of blogging, founding Blogger, the blogging software that was bought by Google and is now one of the biggest blogging platforms online. It was through blogger that Gmail was launched.
So my question to Newsnight for Ev: what's next after you sell Twitter?
