Devs generally hang out in places where the players can't find em.
edit:
As for networking with devs, you generally need something to bring to the conversation.
Not that you need special social skills to hang out with devs, but If you're just getting started and wish to talk about something on a more professional level (making connections and networking), you might come off as rather annoying.
Personally I know dozens of people that "want to make it in the industry" and I find it quite annoying when they bring it up.
Not because of their goal, but mostly because they get ahead of themselves.
I don't particularly care for their "awesome game ideas" or their requests to "introduce them to <game director of game they play>".
In the latter case, even if I do have a direct line to some devs, I'm sure they don't want to bothered by someone without a resume either.
It's hard to put this in words, but basically: it's annoying to talk to someone about something they don't know enough about yet.
What I'm getting at, don't seek out devs before you've got some experience under your belt to show you're more than one of the zillion players dreaming to make their own game.
Networking only works if you can leave a good first impression.
Don't run too fast.
