I have a really hard time finding any kind of social connection that seems genuine and not a front for some kind of business/religious/political pursuit. It's like social connections are seen as merely a resource to exploit rather than being valuable for the actual human connection.
I highly recommend finding something you're sincerely interested in doing, and then finding a group to do that thing with. Could be cycling, robot building, 3d printing, softball, etc. I've had the best luck when it is an event that is not generally attractive to people trying to "network" or hook up, etc; not that it's a problem if some people there are doing those things, but if that's what the majority are doing it detracts from the atmosphere for me, and you, too, from the sound of it.
