My favourite github UIUX snafu is being unable to navigate back to the root repo page when I'm in some sort of complex view, or being able to go to the authors profile in less than like 5 clicks.

Re going to author's profile, I usually just give up, and go to the URL to fix the address.

You'd think clicking on author's name in commit log view would bring you to their profile — social coding, after all — yet it simply filters the log by author.

Just checked, apparently, they do have a tooltip popup in "Commits" log view to go directly to the author, but who has the time to wait 1s until the tooltip's appearance? Clicking on the name simply filters commits by the author, clicking again, just reloads the same page you're already on — but, hey, at least they didn't break the URL addresses yet!
