I [somewhat] recently signed up for a bunch of social networks like Myspace, Friendster, Facebook, Orkut, Flickr, del.icio.us, and others, and then I realized something:  I'm not a social person.  I don't like to meet new people.  I don't like to share things.  I don't like to find out what other people think and do.  I'm not all that interested in these things.  There's always a question on these sites that asks something like, "What are you looking for:  Dating, relationships, networking, friends".  I'm not really looking for any of that.  I'm not really looking for anything at all.  Most times, I sign up for these sites to see what all the hype is about.  Or in the case of Myspace, I look for people I went to high school with and how many of them have become adult film stars.  I'm not looking for someone that plays guitar so that I can say, "Ooh you play guitar?  Me too.  That's cool."  I'm not looking for a place to learn new things or find interesting websites.  I'm just not into the whole social networking scene.
