Did you ever hear anything more?

Here are some other tourism groups that are using foursquare:

They aren't doing it through the "official" brand type page, they just created a regular user and then promote with that account ..... so basically, foursquare didn't do anything for them ... no special badges, and you have to add as a friend, not just follow, but probably still an effective way to connect with users...
