Have you thought about connecting to foursquare data? https://developer.foursquare.com/start/interact

good idea - might use that for the early stages when there's not a lot of usage. thanks!

I was looking into the API and the gnip api also--- gnip provides anonymized data, but it's not clear to me whether they retain age/gender in their anonymized data.

Using the Foursquare API for this sort of data aggregation service (i.e. for stalking people) has been done many times before. Unsurprisingly, Foursquare didn't like it one bit [0] and ended up changing their API to prevent this sort of usage [1].

Cool, it's good to know that foursquare is doing that.

Nevertheless, I think a better way for this app to perform is to wrap around foursquare. I'm already going to be checking-in with foursquare, so now I have to click a second button to check-in using Loca? If mfkp allows users to add their foursquare credentials, then it'll eliminate that extra step.

But I'm also not sure if mfkp is using a "check-in" model or what.
