I used to have TweetDeck for Windows but due to it being a resource hog, I decided to uninstall it and look elsewhere. Maybe it was to do with Adobe AIR.
I have had a search around on Google for a successor to use for Tweeting MoG-related news on the MoG Twitter account and I came across a native Windows application called Seesmic.
When I tried it for the first time, I was absolutely stunned. Seesmic works better than TweetDeck and has the same features as it. The more noticeable difference was that it didnt hog most of the CPU resources compared to TweetDeck.
It really works well on Windows 7 too. I recommend anyone who uses TweetDeck and Adobe AIR to bin them BOTH, and get this native Twitter client.
You can get it for FREE at http://www.seesmic.com :)
