I had a brief time in Amsterdam last summer during my summer travels and it seemed to be a good scene, albeit a little scattered. That being said there are some co-working hubs like A-Lab and meetups like Appsterdammers (http://www.meetup.com/Appsterdam/) and their weekly event Meeten En Drinken amongst other more formal events. Mike Lemur (@bmf on twitter) founded both those and is THE guy I would point you to as he made a similar move from SF to Amsterdam just a few years back. It was a very inclusive vibe and a lot of fun.
