"Strong"?

381 / 6 = 63.5 checkins/user. Or, about 5 per month.

Doesn't seem like a high-engagement app to me.

I toyed with Foursquare for a while but then deleted the app. I'm past the "it's Saturday night, where are all my friends at" stage of my life, and battling some other schmuck for a mayorship so I can get $1.00 off at Starbucks or a free appetizer some place wasn't worth the effort, and leads to an increased spend that far outweighs the mayorship "benefit" (when there is one).

I'm kinda feeling like foursquare is best done as a feature to a larger app or business model.
