Can't seem to find the definitive answer to this. What restrictions should I look out for between the two? I currently use foursquare exclusively, but sometimes there are places not in foursquare that maybe I want to use Google for.
Update
I use the 4sq API only for the name of the place and lat/lng. I don't want to use a combination of 4sq venue data, and Google Places data, for the same place... just want to be able to check both services to pull name/location data.
