Earlier this month we learned that Twitter was working on a Lists feature designed to make following and suggesting groups of tweeters easier, and today they appear to be tackling the big rollout.
Twitter's taking the Google approach and slowly rolling out the new feature bits at a time, so if you don't already see lists as an option (you'll see a big New! box on top of your Twitter homepage if you're in), you probably will in the next day or so. Got plans to use Lists extensively? Want to share a list you've just created? Let's hear it in the comments.
