This is actually where the foursquare superusers come in. You can read more
about what a 4sq superuser
is<http://blog.foursquare.com/2011/05/19/growing-our-superuser-community/>,
but they take on the responsibility of keeping the foursquare database
clean, much in the same way that we do for OSM. Location and detail
accuracy is important to that group.
Mind you, this is actually an exclusive group of foursquare users. My
understanding is that they have to apply or be invited.
Even though this thread isn't about bringing foursquare data into OSM (I
have no idea what, if any, conversations around that have been held), we
should definitely take note that there is an almost parallel community of
extremely like-minded editors out there, and we would be lucky to have them
join our community. We should engage with them and share knowledge!
