Let’s vote on it: Will Europeans use Gowalla, FourSquare or what?

So it’s been nearly 10 days since Foursquare launched its social mobile game ‘ground assault’ into 50 more cities, including a bunch of European ones. But what I’d like to know is who’s actually using it here in Europe? Because, you see, Europeans are already quite well served by location based mobile applications like Qype , the various localised versions of Yelp, and other startups like Rummble .
