Personally, I feel like it's rare that I stumble on a tool and need to read its landing page. If I know of it, it's probably because someone told me about it or it's already part of something I inherited. And that's probably the only way I would consider it anyway. I don't care what their pitch is if I don't know anyone using it. Much more common is stumbling across a repo with tooling I'm specifically looking for (because I don't know anyone doing that specific thing and I'm not looking for an alternative to something I'm already using) and the repo docs are even worse.
