Foursquare

Foursquare is moving to make the list of “Places” one sees when one loads one’s mobile app of choice more relevant. The company announced this morning that it has recently made changes to improve its algorithms for serving up this data, taking into account things like time of day, proximity, and popularity of the venue in determining which places to show you. This should be a welcome change for users of Foursquare.

Location-based social network Foursquare counted its 40 millionth checkin a “couple days ago,” according to a tweet from one of its developers. The number shows that Foursquare’s growth rate is accelerating: Five weeks ago, the company announced that the total number of checkins had reached 22 million.

What’s more, recent acquisition rumors have driven Foursquare hype to new levels. ...

The big day could also potentially be the day Foursquare reaches one million members. According to Co-Founder Dennis Crowley, who joined me on NBC San Diego earlier this morning (see video below), the company had nothing to do with the day except the creation of a special badge — it was devised 100% by fans of the service. ...

For those of you armchair mayors who cheat with your Foursquare checkins, your time has come. The mobile social network has announced that checkins outside the immediate vicinity of the venue in question will no longer net points, badges or mayorships. Foursquare is now using your mobile phone’s GPS location (other tactics are used for phones without GPS) to verify your whereabouts to reward only those that happen near the actual place in question. Checkins that appear to take place far from the venue users are trying to checkin to trigger the “cheater code” and block incentives. ...
