I've started work on a new website: www.raider101.com
The page on this blog that gets the single largest number of hits is the Hit Caps page (currently outdated). I think this shows that there is a real demand for basic, comprehensive information presented in an easy-to-understand format. I adore Elitist Jerks, but it's very advanced, and I think a lot of people just want basic information, rather than having to wade through 50-page threads.
My idea for Raider 101 is to have the basic information on how to play for every class and spec available in a single site that is easy to navigate. I'm also trying for an emphasis on talents and ability rotations, rather than gear. In my opinion, too much attention is paid to gear at the low end, and not enough attention is paid to the other elements. I've written up Retribution to start with, so you can see what I am aiming for.
It's a wiki, so if anyone wants to contribute, feel free. The important part is to keep things simple. The intended audience is not the people who can do 3000 DPS and are trying for 3500. The intended audience are the people struggling at 1000 DPS. After they master the basics, they can go to Elitist Jerks and delve into the deep theorycraft.
It's very much a work-in-progress at the moment, though. If you'd like to contribute (especially non-paladins) feel free to sign up.
