Every forum on SWF eventually turns into a casual vs competitive forum. It's as inevitable as religious factions fighting over the same god.
No, I tell you, it wasn't nearly as bad as it is now. Before I remember some threads in the Melee forum, like the one where Dylan said he wouldn't play Brawl if it didn't have WDing, as well as other threads where people thought they saw WDing confirmed to some degree. The forums moved MUCH more slowly than they do now, newbies tended to not make their own topics devoted to the whole thing, it was somewhat annoying, but still manageable, as it was generally only one or two newbies and they stuck to the topic at hand.
Now, though, the whole thing is just insane. Brawl is getting closer to coming out and thus we an inundated with new posters. WDing and Lcanceling being removed also has created a trend of (somewhat) more useful debate topics as to if/how this will affect Brawl's metagame in the long term, which then tend to get sidetracked by the newbies who post saying "HAI GAIS WHY ARE YOU ARGUING ABOUT THIS GLITCHES SUCK", which then encourages other newbies to post more useless topics on the subject because they never learned how to lurk... I mean, jeez, if you let this sort of thing go on for too long it's not a forum anymore, it's a spam fest. If it doesn't quiet down soon we will need to do *something* to stem the tide until things can return to normal.
