you can essentially do this (post a twitter message from the address bar) in Chrome or Firefox without installing anything if you just configure a custom search engine with the path http://twitter.com/home?status=%s

1. In Chrome, go to Options > Default Search engine > Manage > Add

2. Give it a name/keyword e.g. "tweet" and URL http://twitter.com/home?status=%s. Hit OK.

3. Now from the address bar, you can type: tweet [msg]

4. Forwards you to twitter. Although you still have to click a button on twitter, you could easily write your own serverside twitter API client that could post your tweet without the click.

Yes you can. It would not however poll for new mentions, and direct messages wich OmniTweet does.

Plus you have to wait for twitter.com to load which takes longer and longer.
