As a (somewhat) long time member of the WotC boards, I would point out that the largest population slice I would call disruptive, trolling, flame-baiting jerks have a tendency to be people who show up on those boards for little reason other than to tell people how horrible WotC, 4e, and (strongly suggested by extension, or more frequently, outright said) anyone who plays the system.
There are, unfortunately, plenty of 4e fans who respond with the same misguided vitriol, which is a damned shame if you ask me.
There are things I love about both product lines, and plenty of flaws to go around too, in my (never humble) opinion, but there's a strong difference between disliking something and pointing out its flaws, and a desire to see a product fail or harm befall its creators and purchasers because you hate it.
While I don't really endorse this thread, I'd like to point out something to everyone here:
Swinging (real) swords, building old cars, making your own beer and table-top RPG gaming are all hobbies that share something in common: they have all been replaced by a more modern equivalent, and have a limited "normal" growth. All of these hobbies rely on being passed down by friends, family and local culture, because there is a quicker, easier, more accessible variant of all of them.
What's more shocking is that table top RPG gaming has hobbyists among actors, writers, comedians, porn stars, pop icons, and the rest. In D&D it has a brand recognition that is big enough to be considered a frickin' commercial superpower... But what happens when some new kid tries to take the plunge? What happens when they walk into a gaming store or hop in an internet community board?
"NO FU, THAT GAME IZ RONG AND UR RONG 4 LIKIN IT!"
"NO U"
"NO UR FACE!!! HA BURN"
"IB4TL LULZ"
"PEEPUL WHO PLAY UR GAME SHUD DIAF I HOP U GET TEH AIDS"
We've got a community with a (I pray) minority of incredibly vocal, narcissistic, elitist jackholes that have nothing to be particularly smug about, unless poor behavior and sociopathic tendencies suddenly become an olympic event.
...And we egg them on.
Good job. D&D won't die today, table-top won't be gone next year or even next decade, but with the loudest parts of the community insisting on shouting at eachother, wishing ill on people who disagree with them, and hoping for nothing but misery to the people who play differently than they do, it won't be around much longer than you folks will.
Enjoy it while it lasts, I guess.
