TweetTabs is a slick web interface for on the fly trend tracking and searches. New tabs pop up across the interface, much like TweetDeck would be on the web. I liked it immediately and found value when trying to watch information about a conference in near real-time without killing your own API limit.
They give trends acorss the top for those that can’t think of what to search for. All my tests came back with lightening fast results and started updating immediately. I wish there was a throttle to slow the screen on very hot topics. The time and date show in the upper right of each tweet in European format (just so no US person thinks the dates are wrong).
I imagine the ability to retweet or reply could be in the future.
