So the most favored Rubyist has returned from hiding with a fun new puzzle. Further down, folks are posting interesting stuff about it.
But the finger wagging – people just can't get enough of telling people what they should do and feel. And apparently that's what they want, for behold this top comment.
My point though, is that _why has made it clear that he wants to be left alone, and this HN endeavour seems to violate that. Maybe you're right and it is a new puzzle. And maybe he's back. (For what it's worth I posted that before most of the investigation.) Nevertheless though, given _why's wishes, this makes me uncomfortable, and I don't think it's unreasonable for me to acknowledge that.
That, is of course, crossing the line. If someone wants to distance themselves from an online tag, they should be allowed to in peace.
Now, however, it seems that he's brought that persona back to life. He's posted a new puzzle, and brought his site back. Obviously, he wouldn't do that if he still "just wanted to be left alone." That's why people are excited.
Second, I think you're attributing motives to _why that none of us can possibly know. He's never discussed his rationale for leaving, so I try not to project motives onto him.
