Interesting. What algorithm is this using to make recommendations?

If you're not already, you should consider an algorithm that places less weight on more commonly used tools; right now, a huge number of people add "git", for instance, so it shouldn't carry much weight when looking for similar people and recommended tools.

This could also use a "not interested" or "actively don't like/want this", to filter out unwanted recommendations.

Looks like there are two copies of "Google Chrome".
