All in the US and Canada though.
Social location iPhone app Foursquare is continuing to ramp up the number of cities it supports, adding 15 yesterday.
However, they reinforce the North American focus of the application. Despite adding London this month, 13 of the 15 new cities are in the US, and the other two are in Canada.
The full list:
US: Baltimore, Cleveland, Indianapolis, Kansas City, Milwaukee, New Orleans, Omaha, Pittsburgh, Raleigh-Durham, Richmond, Salt Lake City, San Antonio and St. Louis.
Canada: Montreal and Toronto.
The company tells Mashable that it's rolling out new cities in batches to ensure scalability, so hopefully more European cities are on the roadmap.
Meanwhile, Foursquare is looking to get its keenest users helping clean up its data. TechCrunch reports that it has created a new top-level - 'Superuser - Level 2' - who can merge duplicate venues.
According to co-founder Dennis Crowley, within two hours of upgrading a group of users to that level, 90% of the duplicates had been merged.
