When I came back to the site recently I asked why there were no new posts, the response I got from one poster was that all the questions had been answered!
Webmasterworld shoots itself in the foot sometimes with that. i remember a newbie posted something about link building once (i think it was link building), asking the same old questions that a newbie always asks, and the second post was from a mod saying look in the library before asking. end of conversation.
i'm guessing that newbie has never returned, because 1) he got a telling off as soon as he arrived, and 2) he probably felt like he wasn't allowed to ask anything without trawling through hundreds of old posts first.
i can understand why the old timers at WW (and i'm one of them) dont want to read the same newbie questions all the time, but they shouldn't chase away the very people who might end up asking some new ones. if they had let that discussion run, then maybe someone would have chipped in with a good idea. but it was killed off before it even got going.
