Discourse 13 years ago was very positive overall here (but then everyone was here for exactly the same thing: D&D 3E). It was at its worst 4 years ago (4E) and is currently far better than it was then. Edition wars still exist, but many people have tired of them, or realised that they were unwittingly entering parody territory. Plus the worst offenders left so that they could tell folks on other messageboards that they were banned for liking/not liking 3E/4E.
Plus we're - slowly - becoming a general RPG site. Our Tabletop Gaming forum is still fairly quiet (but busier than it was years ago when it was lower down the forum list and sequentially called a variety of names, such as "Other d20 Games", "OGL Gaming", etc.) - that transition has been taking place very, very slowly over years, but more so since the hack in December; and I'm pleased that big new RPG releases like Numenera, 13th Age, Shadowrun, and Edge of the Empire are getting play here. That transition is partly by necessity, because history shows that hanging your hat on the fortunes of one company (WotC) may mean that you do well when they do, but when they're not doing so well, you struggle too; diversification helps with that. Boardgames are finding it harder to gain traction; BGG is very cool and has quite the monopoly! The D&D forums are busy as ever (though being in-between D&D editions, we anticipate a very large increase in activity there once D&D Next finally releases in non-playtest form).
I still feel very comfortable with EN World's unofficial position. Some folks choose to compare a fan site like this with official sites like wizards.com, paizo,com, and others, as though there were some kind of rivalry. If there were, then this site has never, ever rivaled any official site - especially WotC or Paizo - in terms of size, and never will. This place is a smaller, friendly alternative to the official sites, and always has been.
(Re. registration dates - yep, 2002 was a big server crash; we had to completely restart.)
