If you love Twitter and if you use desktop tools to keep on top of Tweets, then you should give Tweetgrid.com a try. It has a new interface since I last tried it and now you can perform most of all the functions that you can normally do from famous desktop based tools TweetDeck.
I loved how I can now just forward a tweet in my email from within the browser. You can also save your configured tweet grid as a bookmark or share it to friends. Awesome tool. It deserves to be the web tool of the week.
