I mentioned Plurk earlier, but now I've written up a full review of it for MakeUseOf.com. Check it out and comment what you think. I have really enjoyed testing it out...so much so that I'm almost certainly going to use it in the future. It's really pretty fun! Plurk on everybody!
At the bottom of that page you can find everybody from MUO who uses Plurk, too. Friend us up if you like!
