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).
We* remade you our developer website. The new site is not only prettier, but cleaner and easier to navigate. We also beefed up a lot of our explanations of best practices / platform policies which I know all of you will appreciate.
* And by "we" I really mean Alice (@ byalicelee), our most recent platform intern. She rocks! We're on the look out for more student interns, so drop us a line if you're interested. (And for all you non-intern peeps out there, check out http://foursquare.com/jobs)
