I didn't feel the need to downvote you but I think the reason is pretty clear. You're making an unhelpful and not very clever joke, and then making up a future 'version' of the app for no discernible reason.
I think the idea was to highlight the most obvious use for apps like this. The very idea of how easily one could be made by connecting easily available information such as Foursquare checkins, Facebook profiles, tweets, Instagram photos, all neatly tagged with addresses and geographic coordinates allows anyone with such disturbing inclinations to piece together a fairly accurate picture of whoever they want. This app offers a nice menu of easy targets.
