The Twitter phenomenon just keeps on getting bigger, and F1 isn't about to step aside and miss out. A few teams have picked up on the concept, plus some influential journalists have also started sharing their thoughts in 140 characters or less. Here are some of the ones I have noticed so far:

Renault F1
Twitter ID: rf1paddockpass

These are mostly links to press releases and news items on the Renault F1 site, however, there are occasional quotes and I expect there will be some news snippets in the future. Definitely worth keeping an eye on.

James Allen
Twitter ID: Jamesallenonf1

Allen commentated on ITV for the UK coverage last year, and he writes for the Financial Times. This year, he's got his own blog and is "live-tweeting" during all the sessions, so if you miss anything, this may be the place to be.

Force India
Twitter ID: clubforce

Another Twitter account that is used mostly to link away to other things on the official site, however there is more than just news. Recently, there has been scope to wish Sutil and Fisichella birthday greetings, plus news of a discount at the merchandise store.

Radio 5live
Twitter ID: 5LiveF1

The UK radio coverage is provided by BBC Radio 5live, and they are tweeting some interesting backstage snippets during each race weekend. The updates aren't as regular as you might hope, but are usually worth waiting for. You are also quite likely to get a reply, unlike with the official team Twitters.

McLaren
Twitter ID: TheFifthDriver

I'm not sure why they are called the Fifth Driver, but there are plenty of updates here from both site update acknowledgements, to news from the track during each race weekend. Don't expect scoops, but it's good to follow the official word.

And of course, you can always follow me! My Twitter ID is mrschristine but I don't solely discuss all things Formula 1, other things creep in there as well.

Also, if you have got this far and are confused about what Twitter is, there's a great article by Jill on the subject.
