I think adding "in Emacs" to the title of an article published on Mastering Emacs Dot Org might be a bit redundant.

Scrolled over the title (thought it was some programming algorithm concept) and then by chance I've read the site name saying it's about Emacs which prompted me to open the discussion.

Maybe on some setups the site name is not as easily visible as the title?

What’s visible on the HN page is “masteringemacs”, which is just nonobvious enough to parse (“master in <whatever>”) that it doesn’t register.

some times a bit of redundancy doesn't hurt

Is everyone supposed to comprehend the domain name of the post?
