HootSuite released just yesterday (July 31) a substantially updated version of their Twitter client. I now think it''s superior to TweetDeck because with Hootsuite you can: 1. Manage multiple profiles (also true in TweetDeck) 2. Schedule tweets (big shortcoming of TweetDeck that you can''t do this) 3. Shorten links & track statistics (TweetDeck offers bit.ly but I prefer the ow.ly shortener) 4. Create groups (TweetDeck does this, but not well - HootSuite is superb!) 5. Integrates with Ping.fm (can''t do that in TweetDeck) 6. Tabbed view to manage profiles, groups & search columns (big advantage over TweetDeck''s "flat" layout) 7. And, the knock-out punch - HootSuite is web-based, whereas TweetDeck is a massive resources hog on your desktop
