Doesn’t everyone run a server at home?

Sometimes I loose track of how much of a geek I am…  I just take for granted my 1TB+ server running mythtv and serving up ipod converted videos,  also hosting Jinzora for music access in the house, a couple of VMware images for other services etc.  But then I start talking to someone on my commute and they laugh nervously or ask  “whats a server” and I realize, i’m a bit of a geek!!
Please tell me im not alone!
