Twitter can definitely be frustrating, but also very interesting. It's certainly getting a lot of publicity lately, being mentioned on Rove on Sunday night and on ABC radio yesterday too. ABC management are encouraging all of their staff to start "twittering".
If you just use the main twitter.com interface it can get very clunky very quickly. 3rd party applications like tweetdeck make it bearable and help to filter the signal from the noise.
