I was very confused for a considerable time when people would point me to GitHub for a description of a project, because there didn't appear to be a description, just a repo. Was I supposed to build it to see what it was?
This seems very silly in retrospect, but there really was a month or two where I just didn't understand at all what I was supposed to be doing there, and I've never forgotten it.
And why? Why is it so critical that the first thing people see is the file structure, and not a description of the project? Echoing the article, I suppose it makes it "about git", but even when I'm interested enough to start poking around, I'm more likely to clone a project than browse through it on the site.
It just feels intentionally obtuse.
