Cute idea but it doesn't work for me very well. There's a project that takes up 90% of my time and I'm a major contributor but it only gets a single line under "Contributions" while useless old projects that nobody uses any more are highlighted under "Popular Repositories" with several lines of information.

I think the heuristics need tweaking a little. "Creator & Owner" shouldn't carry as much weight and recency should carry more.
