2010 was yet another year when Twitter never seemed far from the headlines, both for innovations such as its new interface and for giving the likes of Kanye West a platform for bizarre pre-album ranting. But which of the millions of celebrities, bloggers, journalists and ordinary Joes and Janes scored the most 'retweets'?

Now we know, thanks to Twitter helpfully releasing a list. Kanye's 'I'm sorry Taylor' - which ended a really long dark-night-of-the-Twitter-soul - comes in at number 8, just behind Rihanna tweeting that she caught a glimpse of Justin Bieber's abs in a restaurant. (Er, OK.)

Who's number one? You'll have to see for yourself. Hint: it's not, surprisingly, enough, The Bieber, though he sure is in there.
