Github edges out Hackmd modestly on homepage messaging, 83 to 78. Here's where the gap comes from.

Github is clearer about what it does (100 vs 46 on clarity). Github's hero ("Search code, repositories, users, issues, pull requests...") names something concrete, while Hackmd's ("Join a global movement") stays abstract. Hackmd has stronger CTAs (85 vs 60). Github triggers decision paralysis with 10 competing CTAs, while Hackmd keeps it focused at 5.

Both sites use the "Community / Movement" positioning archetype — they're competing on the same narrative, which means differentiation has to come from execution, not framing.
