I got intrested in experts-exchange along time back. I had an insane project to emulate MMX insturctions, and didnt know what I was doing, and in the process stumbled onto this site. Asking a few questions here promptly showed that the projected was doomed, but I stuck around, because I enjoyed answering questions, and getting the free t-shirts. My craze for question answering is over, but I still remember the site fondly, although I'm amused to see I'm still in the top 15 experts on several catagories.
