This got me thinking: if I could “pocket” my data, restrict certain tweets to certain geographies on the OUTBOUND side of Twitter, then that’d be neat. I mean, most smartphone apps of Twitter have my location. What if they could say to the API, “Only send this to people within 25 miles of this location?”
This is a good example of what I mean when I say that foursquare is just the tipping point of geo+social services.
