SplitTweet at http://splitweet.com is a great tool if you have a number of accounts on Twitter.  Rather than switching between them from time to time in order to Tweet, you can set an account up her for free and bring all of your accounts under the one roof.

Splitweet will display the Twitter feed from all your accounts at once, or you can turn individual accounts off and on.  When actually tweeting, you can pick an account to tweet to, or you can do a broadcast message across all your accounts at once.

Some very flash technology this and very useful for handling multiple accounts.
