I use Twitter. A lot. Because I gather good ideas, links, quotes, and friends there. And since I'm following over 600 people, I could use some tools to make it work better. I had just started using the IM feature to get automatic updates from everyone, when Twitter disabled it.
I've tried Twhirl and Snitter, and wasn't satisfied with either. But after a couple of days, TweetDeck has become a favorite. It's another desktop Twitter app that runs on the Adobe Air platform.
You get more than one column, so I can have the main stream, replies, and a group of friends all on screen at once. That groups feature is a huge thing. I can put people into any kind of group I want, and watch them in their own column.
I don't like the white text on black, but I don't see any way to change preferences or settings. I hope that's on its way.
And how do I favorite a tweet? No idea. And I favorite a lot. Hundreds.
But it does make it easier to keep up through the replies and the groups. Nice.
