Out of curiosity, what are other people working on for their projects?

I have been downloading messages off of Yahoo's finance message boards. I am going to implement Topic Sentiment mixture modeling on these messages, as described here:
http://www2007.org/htmlpapers/paper680/. It will be interesting to see what kind of results come from this message set, and to see if this model is a viable way to filter the messages that are on Yahoo's message boards. There are many off topic messages on the board, but this could conceivable let people view messages that fall under certain topics or sentiments.
