Businesses included on Foursquare will also now have access to more data on the users who have checked in at their establishments within the previous three hours -- although users can deactivate this permission.

If Foursquare takes flak for its announced changes, it certainly won't be as much as that brought on by another social network, Instragram, whose policy changes earlier in December provoked widespread misunderstanding and dissent.
