That's never fit my definition of work though. Work is where I go to work, to get stuff done with motivated people. I mean, I'll be friendly with coworkers, sure... but I didn't necessariliy choose them. Kinda like highschool or college - these people are around because they were placed there. A friend of mine called this "Friends of geographical convenience" once. I have lots of people I get along with at work... but would I invite them to my daughter's wedding? A child's graduation? Would I loan them money if they were desperate? Would I help them move? Could I count on them to help me in troubled times? Probably not, cos people move on from jobs pretty quick. Work friends are kinda like Facebook friends. My real friends and I share more common interests than just computering. ;)
That said, I do have a couple of friends I met through work. But that's different than using work to find friends, I think.
Maybe I'm wrong. I don't know. Just thinking out loud I suppose.
