Totally agree. The only use I see is when you're simply searching for projects/solutions and you want to quickly ascertain popularity and language. That said, I'm not sure I'll remember the color-language relationships without a lot of work that I'm not interested in performing.
I think there's a disconnect in the use case of you and the OP compared to some other people (like me). 90% of the time when I'm looking at a Github repo it's for a new project so things like language composition, number (or existence) of tags to download and clone URL are all very handy. Only 10% of the time am I looking at a project that I'm already intimately familiar with.
