Foursquare's new Swarm app now available for download

A few weeks back, Foursquare announced Swarm — a new app that aims to help track down your friends when you're out and about. Using Swarm, you'll be able to see which of your friends are nearby, even if they haven't checked in somewhere. You can also suggest plans to your Swarm friends, then text those that are interested in tagging along.
