I guess I run seti@home for two reasons. It's just "out there" enough to hold my attention and I would like a bit of the fame for finding "the signal". Besides, it would be cool to be the one to find "the signal" even if no one knew it was me. Did I mention in my previous userprofile that I am a BIG Carl Sagan fan?
