It was also open season on anyone saying anything even remotely neutral about 4E after the Pathfinder announcement was made, and with only token moderation at best.
If anything, I think ENWorld is and has been much more neutral than Paizo's echo chamber has been.
I never even got to the 4E forums on paizo.com. I went to the Pathfinder RPG forums to make comments regarding the first 2 alphas and the mood of teh forum and a complete lack of moderation, plus some of my posts being misplaced by the system (they showed in my posted list but not in the actual threads), I didn't feel it was worth the effort.
While the wording might be considered provocative, I would suggest that one of the biggest problems with this whole community is members who take a slam of a game system created by a large company as an insult to themselves.
If I said "All 4e fans are idiots", that's me insulting them...if I say "I see 4e as a complete abomination" (which is more extreme than my own real view), then why can't people be secure enough on their own to not find offense in that? Are people really that insecure that they can't allow anyone to speak ill of their favorite version of a little game where you pretend to be wizards?
This is kind of the nature of fanboys. Say something bad about Wolverine, the Green Bay Packers, Clay Aiken or the gods-foresaken Cincinatti Bengals (one assumes they have fans left) to a fanboy(girl) and you're in for a world of hurt.
Now take a place like ENWold, with its high concentration of the fan-like variety. It can get ugly quickly.
And herein lay part of the problem, IMO. The EN World News Page became so overwhelmed with 4ed news, even of the most trivial matter, that 3ed news was either totally neglected or buried under its weight.
Even now, several months after launch, the news page is awash with every piece of tivial news - in a way it never was for 3ed.
ENW is a D&D website. D&D itself was changing and people wanted information on that change. Many companies halted production of titles or at least cut way back on production in the 9 month interim.
I do remember when threads arose accusing ENW of ignoring PFRPG news and Morrus and company pointed out that it wasn't being submitted. The majority of news items on the site (from what I can tell) are scoops from people outside the admin membership of these boards. After this was pointed out we saw people specifically uploading PF news and magically it appeared on the front page.
WotCs internet persence and website was even worse (scary to believe I know) when 3E came out than when 4E came out. They were largely releasing teasing info in Dragon and Dungeon. Once a month we would get flooded with new bits of info and occasional bits we got in ENW or wotc forums and the occasional web updates. We had a concentrated thrice a week for half a year series of previews from WotC this time around. I'm not surprised at all that there were more small updates (not to mention the constant threads about who would/would not go 4E and later about the GSL)
