I'm in the process of building out a simple Facebook app and had trouble finding a way to "rank" friends, namely who was closest to the logged-in user.<p>So, I just built my own web service to do so: Facebook Friend Rank.<p>I bundled the whole thing as a web service rather than a gem or stand-alone library because I'm sure most people would want something they can just plug-in (or make a call to) without worrying about the complexities of running background jobs, setting up another service on their boxes, etc.<p>I think Goliath serves as a solid underpinning as this project evolves. The evented nature of the web service should scale well as the ranking algorithm evolves to process multiple API calls in parallel.<p>All told, I'm happy to launch the project to HN, if only for some initial feedback.<p>Thanks!
Give this project a quick shot & see who your "best" friends are here in the demo app (bundled with the project):<p><a href="http://facebook-friend-rank.herokuapp.com/demo/index.html" rel="nofollow">http://facebook-friend-rank.herokuapp.com/demo/index.html</a><p>It asks for & requires the read_stream permission to scan your activity log and see who you most frequently interact with.<p>The click "Apply Friend Rank" to start the ranking process.
