Not sure if it's quite right for beginners (stuff like Samurai Flamenco kind of require some exposure to various genres), but a good recommendation chart overall.
Sticking Gundam in the "hundreds of episodes" section is kind of weird because it's mostly separate series. There's an order to watch them in if you're planning on watching hundreds of episodes, but it's not required.
And it seems like both the "MMO Adventure" recommendations are... not recommendations. If anyone wants an MMO anime, both those series are fine and there's also stuff like .hack//SIGN, Danmachi, and Ixion Saga DT that are all totally different.
