Barack Obama does it, Stephen Fry does it and Britney Spears does it too. Twitter is the latest Web 2.0 tool to get everybody talking - and people and programmes all over the ÃÛÑ¿´«Ã½ are at it as well.

For the uninitiated, Twitter is a very simple idea. You answer the question 'what are you doing?' in 140 letters or less, as often as you like. Other people can then sign up to 'follow' you and receive your updates. They can also reply to you, either in public by using their own update or in private via a direct message, a bit like an email.

Generally people use it to gossip, gather information and share news - from the mundane (at time of writing Twitter user Stefnet is 'enjoying a cup of tea') to the significant (director of Global News Richard Sambrook looked to Twitter for UGC updates during the Mumbai attacks).

And now ÃÛÑ¿´«Ã½ Somerset is to start 'tweeting'.

We'll be using our page to inform you of what's coming up on ÃÛÑ¿´«Ã½ Somerset's radio shows, including how you can get involved with Have Your Say with Emma from 9am.

You can also find out the latest news and sport headlines from around the patch.

So why not get involved!
