Sponsoring Open Source Developers
I am nowhere near their numbers, but I run a boostrapped business that would never be possible if it wasn't for Clojure (and specifically ClojureScript). A while ago I decided that I'd be permanently setting aside a percentage of revenue that will go towards sponsoring open-source developers that write and maintain libraries that my project uses. The contributions are very small, but growing steadily.<p>I think what matters mostly is not the contribution size, but the mindset. If every company using open source contributed at least a little, we would have a healthy ecosystem.
