Have you ever wondered what people are twittering on about on Twitter? Well now you can find out with Twitterment. Twitterment is a mashup using Twitter, JfreeChart (graphs) and Lucene (Search) open source libraries to be able to search and analyze what terms people are twittering about. It is really cool actually and seems to work great. It was a little slow when we tried it but maybe it was just under load at the time.
There is also a compare function where you can compare the stats for two terms.
Twitterment is hosted on UMBC (University of Maryland Baltimore County) and we assume it is a school project of some sort. The credits lead back to two PHD students and Professor Tim Finin. Tim Finin is a Professor in the Computer Science and Electrical Engineering Department at UMBC, the University of Maryland Baltimore County. Finin is a member of the UMBC ebiquity group where he is working on projects involving intelligent agents, the semantic web, pervasive computing , and mobile computing.
There is also a stats page that says that 368,103 posts have been indexed, there is an average of 16,500 tweets / hr and a summary of the number of tweets per day (90,000 on mondays!).

We are not sure when the data collection started or how long it will be retained but this will be a cool project to watch.
Below are some screenshots for a search for the term iphone. As you will see, Google maps is also integrated in the results so you can see where your searched terms are in the world..
