I am based in San Francisco, but would love to connect with people around the world.  
Anyone with recommendations for local message boards to visit for international cities abroad?

Thanks!

Not sure what type of message boards you're after, but if you have a specific hobby or interest then look for boards that cater to such in other countries.

For instance, if you like photography and the Alps then you can search Google for "photography alps tips forum" and dive into one that looks interesting, especially if you speak the local languages.
