tweetmeme — what’s popular when

tweetmeme is my new toy for watching what’s going on in the Twitosphere. It allows you to watch for any terms and get stats for the last day, week and month. I particularly like the categories, where you can see which Twitter topics are recently popular.

If you search for something like #RPattz — a recent trending topic as today is the boy’s 23rd birthday — you can find out which of the millions of inane tweets about Robert Pattinson were the most popular. This is the most useful feature, I think, of the site.
