No, we're not gonna "make every title a puzzle"—that would be "the opposite extreme".
This has no effect on YC pro or con, it's too inconsequential. Also, we don't moderate HN to be YC-serving. See my comment upthread. Doing so would not be YC-serving anyhow, just idiotic.
Domain names are part of the title on HN, so the title does say Reddit.
I'm glad you know who "spez" is now! See, that wasn't so hard!
About titles: I see you get complaints about titles. I'm not sure if people understand how often commentors will respond to the title. I've submitted articles and seen that people haven't read the article but have responded directly to the title.
But also, it's pretty hard for submitters to understand what to change about a title. And the desire to provide a descriptive title is strong, and there are no reminders when submitting about not doing that.
