Almost forgot! In the ramp up to launching the site, we silently launched a new endpoint but didn't tell anyone.
The endpoint returns a list of venues that are "similar" to the specified venue, based on check-in overlap. Use it to build that Pandora-meets-foursquare mashup you've always dreaaaaammed about (or do something else amazing! no pressure).
