I know. That’s kind of true for all of us. But yet I believe this is not that important. Specially not important enough to put the language like a badge of honor beside the project’s name or description in the title, like how these “written in Go”s are.

If a projects seems interesting enough for someone, it’s more than easy to see what language is it written in. BTW, that’s how things work: you don’t decide to contribute to a project because it’s written in your favorite language. You first have to like the project itself, and if it happens to be in a language you’re comfortable with, you may contribute to it.
