A while back on the B2B Marketing Posse blog I wrote about using TweetDeck  (along with Google Alerts) for managing your online reputation (still a good idea by the way) but this Cool Tool does a lot more that just that. It is a social media dashboard that helps manage your online social channels (despite the name, this includes Twitter, Facebook, and others). You can schedule tweets and status updates, trigger email alerts, and organize “life streams” in order of importance so you can easily separate the wheat from the chaff. TweetDeck is available as both a free desktop application and a mobile app.

At the time of this post, it appears that Twitter is in a bidding war for TweetDeck with UberMedia, a leading developer of popular Twitter API-based apps like Twidroyd.

{Ed. Note 5/24/11: Twitter acquired TweetDeck for $40 million in a mix of stock and cash, making its creator Iain Dodsworth an instant millionaire.}

{Ed. Note 12/8/11:  A new “rebranded” TweetDeck was released, dropping support for LinkedIn, Google Buzz, Foursquare and MySpace. TweetDeck switched from using Adobe AIR to native OS for desktops and open-source WebKit for browsers (e.g. Chrome and Safari).}
