A long time ago, when 3E saw the white light and was spanked to make the first sound, the D&D Website began to slowly mature into an awesome collection of new content.
Articles we all enjoyed like Monster Mayhem, Epic Insights, Spellbook, The Mind's Eye, Fey Feature, and more were blooming by the month. The Web Enhancements for the products you bought were just as good. It was extra goodies to grab for free every month for being such a good customer. Even Forgotten Realms enjoyed its share such as Portals of Faerun, Wyrms of the North, and Spellbooks of Faerun.
However, in stepped the vile bean counters who foretold the coming doom of this "Free Content". And month by month we began to see the free material go away. No more new monster or converted monster each month, nor more new spells, no more new psionic material, no more nothing but boring, dry and flavorless articles such as "SAVE MY GAME: Help, my players are ruining my life" and "WATERDEEP NEWS: People are disappearing after using their bedpans." or "Apply 10 of these templates together and you have the Supercalifragalisticexpialadocious Dire Flumph" and even the Web Enhancements were just as lame.
So endeth the Golden Age of the D&D Homepage and its myriad of wondrous web articles.

Ok, on a more serious note, that's basically what happened. They did away with the cool stuff on their site because the authors of the web articles were told to no longer produce content that they could possibly sell in an upcoming book. This means no feats, spells, monsters, psionics, incarnum, maneuvers, epic material, whatever.
I have heard from a few WotC employees such as Andy Collins and Mark Jindra, for example, that have stated they are planning to bring back more "crunchy" web content. I guess this must be what they mean.
