Since everyone seems to be making a github application, I thought I'd share mine.
It's an aggregated view of all of a given person's github projects, as well as easyish lookups for linkedin/stackoverflow/hackernews. It attempts to determine both productivity (how much code did this person write?) as well as impact (did anyone care?)
I'd love any feedback, but go easy on the number of simultaneous searches as I'm trying to play nice by github's api limits.
