Version 1.0 of Power Twitter, an add-on for Firefox created by Narendra Rocherolle at 83 Degrees, was just released. If you use Twitter and were excited about services like Tweetree, this is something you’ll want to add immediately. Power Twitter moves Twitter Search, inconveniently located on a different subdomain, right into the Twitter site itself. You can also just search a single user’s updates from that user’s Twitter page. Twitter should have long ago integrated a search box directly onto the logged-in Twitter home page. They haven’t, but Power Twitter fixes this. - alex johnson
