I'm using a peak detection algorithm to find which repos are spiking in traffic and rank the uptrend based on a normalized growth curve. This filters out all the well established repos and actually uncovers new trends and launches. Hope you guys find it useful!
Some notable features, there's also a better interface to search topics on github as well as a curated topics section: http://www.gitlogs.com/resource-guides http://www.gitlogs.com/search
Appreciate any feedback,
