Huh, I never ever look there. When I went back to check I saw "blogspot.com". On third check I finally saw what you meant, "morepypy". I accept that helps but not all humans / tools (search/alt readers) are going to be looking at ___domain. We're lucky in this case ___domain gave a clue. Posters should not rely on this, they should be mindful of how their submitted title will be read/interpreted in context. They only get to post it once, we have to read it many times.
Too bad it's a subdomain, I use the ___domain to guess a little what articles are about but I swear I spent 15 seconds trying to understand if it was clojure (core, stm both clojure lingo) or not. Anyway, first world problem.
