You know how much we love twitter around here. It’s a great tool not only for keeping up with friends, but also for finding out what’s happening anywhere around the world.

And a new service will let you keep track of what’s happening in Cedar Rapids, as well. Citytweets.net is a new service that aggregates tweets from and about some cities around the U.S. and the world. Proving that we’re on the cutting edge here in Eastern Iowa, Cedar Rapids is one of only 21 cities included in the list so far.

There are other ways to search for that, obviously, but this is nearly real-time, which makes it quite useful if you’re wondering what’s happening right now.

So if you’re a twitter user, how do you keep up with the things you’re interested in?
