When I was in Berlin a couple of years ago I had checked out what hackerspaces existed there ahead of time and I'd chatted briefly with some of the people at one of the places through IRC. I was only staying in Berlin for a few days so I wasn't looking to build any long-lasting relationships with anyone (though there is nothing wrong in networking even if you're not going to stay some place) but I met a lot of friendly people and a couple of them were so welcoming that if I wanted to I think I could have built some pretty good relationships with them.
