I think this might be a good opportunity to consider, what are you looking for in a good friendship? Are you looking for confidantes, or for people to go places with? Are you looking for people to hang out with 1-2x/month regularly, and then perhaps occasionally in between - what level of friend-committment are you seeking? If you are looking for a 1-2x/month sort of thing, where you can get to know people through regular meetings first but then begin to engage 1:1 or more regularly after you've learned something about them, what about something like a book club? I have been in a few book clubs in my time and they always provided a good social outlet. I also think that a book club may be a less likely place to find superficial people. Of course, I guess I would advise that you check out their reading lists first before making that call :)
