Linux!
I was just thinking the same thing. All of the linux users in my household are conservative-leaning independents, although the sample size (1) is probably too small to draw any legitimate conclusions.
My purely anecdotal observation is that linux users are generally hardcore computer geeks who do not ascribe to conventional political affiliations.
Linux users probably lean libertarian... they are DIY.
I know a few Linux users and I've always wondered if someone who knows a good many of them could tell me whether being conspiracy theory nuts is common among Lunix users. All the guys I know who are big users and advocates of Linux are major league conspiracy theorists whether they're young or old. Maybe it's a clique of conspiracy nuts around here who went to Linux and are an exception or something, but it made me wonder. Regards
