Not sure whether this is an April Fool's act or not, but the optics aren't very good regardless. Someone posts that they're bailing on 4e and going back to 0e (a perfectly reasonable decision to make if the situation warrants) and gets flayed sideways for it...that alone is bad enough; ENWorld already seems to have gained something of a 4e-or-the-highway reputation, deserved or not, and this plays right into it (hence my nagging suspicions of prankishness). But the OP is made by a moderator, and while I don't know the personalities behind the scenes, this sets the others mods and admins off such that the thread gets closed 3 times, moved at least 4 times, and strewn with words in Bad Colours, all over top of a reasonable discussion of the relative simplicity between editions.
So, what gives?
For my own part, I just started a new 1e-based campaign a week or two back, and a mid-week e-mail from one of the players really summed it up for me: "...it's good to see the game going back to its chaotic and non-serious roots!" This from someone who's been playing for 28 years and has never even tried 3e, and who had a character die in the new game's very first session!
Rel's opening post here - whether serious or not - has it right.
