I am a native Earthling (Minnesotan to be more specific) and cannot imagine living anywhere else*. I make my living as a web developer in the Minneapolis area and I am into science and technology. Carl Sagan, may he rest in peace, is my greatest hero. Mr. Sagan's "Cosmos" television series on PBS many years ago fueled my enthusiasm for space exploration. I follow the American and international space programs with great interest. I am single, but only because many years ago I vowed I would get married only if I can honeymoon on Mars. I'm still hopeful.

Thoughts about SETI and SETI@home
Do I think extraterrestrial life exists? You bet I do. Maybe that's just hopeful optimism, but when we finally do make contact, I'll get to say "I told you so".
When I found out about SETI@home, I jumped at the opportunity to participate. I have had one or more machines running the client since May, 1999. I don't care if one of my machines processes the packet that confirms life beyond our solar system or not. That would be cool, but I don't need to be "the one". I just want it to happen. Sharing otherwise idle computer cycles for a worthwhile endeavor is simply the logical thing to do. As of yet, no one has convinced me that I'm wasting time or effort. I'm not even wasting electricity since the machines I use would be always on anyway. I can think of no reason to NOT participate.
