TLDR pages
The issue I have with this kind of projects is that people quickly accept that reading manpages is boring and that they should only use `tldr gcc` or a quick stackoverflow lookup instead of actually learning how to use their tools. It’s like learning how to fish vs. bying fish at the supermarket. Sure, if you know how to fish you can still buy at the supermarket if you’re lazy. But if you don’t you’re stuck with what’s at the supermarket.
