I resent the words "geek" or "nerd" for someone who is interested in technology , or the sciences. To me it carries a negative stereotype. Does a person who likes to play the guitar call themselves a "music geek" ? Or is a person who likes sports a 'sports nerd" ? What's wrong with the simple old fashioned idea of an "electronics hobbyist" or a "person interested in electronics" ?
And as far as weird people go, well I think people who consider themselves "normal" in that their only interests in life are watching the ballgame, drinking beer, and mowing the lawn, or other superficial activities, to be weird. How can anyone go through life without any kind of deep interest in anything other than trying to be a carbon copy of the guy next door. Of course this is highly subjective but it's how I see it.
