The best roomate I ever had (besides my wife 

 ) was my best friend, and the worst roommate I ever had was my then cousin (by a now divorced marriage).
Note:  I wasn't the reason for the divorce.......his father was a cheatin SOB.
But, even my best friend that I got along great with when we moved in, after I moved out, wew needed a good 6 months to start talking again.  Not because of any bs......just needed some time apart.  But, on the same hand, we both lost our jobs at the same time, and I was tech, he was marketing....so back then....for every 5 calls I'd get about an interview (not just a recruiter mind you)....he'd maybe get 1......so I found a job a lot quicker, and had to loan up some $ for groceries and stuff.......And then to top it off.....our apartment got flooded by some idiots above us who moved out, and left the water on after they disconnected the washer.  But, if we weren't best friends back then...I doubt we'd even be talking now.
Aside Note:
One time I roomed with a guy I worked with in college, and nearly every night, when he wasn't screwing some new random chick, he was puffin on the green machine.
Furhter Aside Note:
My cousin, mentioned above.....other then personal reasons....one of the hardest things to adjust to with living with him, was that he loved to hang out with ppl from the hood......I'm not talking about college people either.....but questionable characters in some circumstances.  (I learned, after I moved out, that my cousin was selling pot).
So.....the moral is......doesn't matter.  Either way, roommates can stink, or they can be fun.  But I agree with the other posts, that the best way to meet new people is to go for broke.  But on the other hand, it'd be cool if you had a cool-guy already to move in.
shite! 
 My wife......she roomed with her best friend from 4th grade on in college, and in the middle of her senior year, that girl turned into a mega-b!tch.  For whatever reason.....we never knew....but she just decided in the middle of the summer b/w junior and senior year that she wasn't going to room with my wife anymore.  And they never talked again after that.  When we saw her on Graduation day, my wife tried to make amends and be nice.....and walked up to talk to her.  Her B!tch friend, just loooked at her and walked away.
