1) I think extraterrestrial life exists, but I don't think we'll met the E.T. till several shuttles :D will walk in our galaxy. MARS...YOU ARE THE NEXT!
2) Yes we should, but the 'others' can find our Bill Gates' programs very 'user friendly'? :D
3) I run SETY@home because...it's SETY at home! WHAT A WONDERFUL OPPORTUNITY!
