The author logic for the header and tabs seems pretty reasonable because the arguments come from ideas from most UI kits around, but after the break the article clearly states a lack of knowledge on git and how github was designed around that. Thats one take i`d criticize on github design, it does fail to explain how git or github works, but I think the platform was designed as a hub for git users and does great on that. I think we can agree comparing to other similar plataforms github has the most straightforward design, so much that is used beyond coding. Some people are running communities on it, with colaborative forums using issues and plain text documents formatted using markdown. Its quite remarkable. The intent of the article was good but as some of us programmers would say: if it aint broke, dont fix it. :)
