Foursquare is something that became wildly popular at the same time smart phones were becoming more and more ubiquitous. It is a cool sort of "Hey check out what my new phone can do" kind of tool.

As smart phones are becoming more the standard and less the shiny-new-thing, though, Foursquare and the like are turning out to not actually provide that much value, and are losing their stickiness.
