Plenty. There's not a lot of Malaysians on here, so many tend to drop me an email when they figure it out. Most hang around the same communities (hackers, YC, tech, etc) so we end up knowing lots of mutual people too. It's a small world here.

There's also meeting people by proxy. I find another community from here. People on that community are friends with one another. Turns out those people browse HN too.
