hey SNG,
good post. my reasons are less altruistic. i've learned more here than anywhere else and i guess the more you read here the more likely you are to write as well. plus, this is the only place that i can freely associate (ugh...ugly word...interact) with so many other free-thinkers that demand proof before belief. the logic that certain posters here have is just awesome to me and helps me remember that i'm not crazy. (i live in the heart of texas for crying out loud...sanity is sometimes hard to come by)
