As I remember, It pulled Foursquare sites. So if you had special places you made, it would have those.

Which I think is Swarm now.

Yeah quite a bit of things have broken over time. We did a bunch of stupid developing choices when first starting, that just don't work anymore. For a site that doesn't run a framework I'm surprised it's still running. We've been working on a better version but it's been slow going with our regular jobs getting in the way.
