If you are playing with Social Media, you’re aware of TweetDeck, the Twitter-centric system that helps organize that mass chaos that Twitter can devolve into. If you are just updating your friends of your comings and goings, particularly via SMS, ignore TweetDeck, but if you are monitoring and participating in far ranging online conversation, TweetDeck forms the center of it.
Custom Searches let you monitor stories and discussions, and with the new version, the directory makes it easy to add discussions and other topics. TweetDeck supported Facebook Status updates, the original system that Twitter appeared to copy and enhance, but now TweetDeck is integrated with Facebook for tracking all sorts of information. TweetDeck is also adding MySpace support, the popular service that seems buzz free but with many active users.
Mashable also seems to be big fans of this TweetDeck upgrade.
