It's awesome to see more quality online learning for animators is starting to pop up online.
David Weinstein's Digital Apprentice Workshop went online 4th of July and after a quick look at his site, it looks like a great addition to Jason Ryan's Tutorials and Keith Lango's Video Tutorial Service.
Animation is such a huge topic, so getting inputs and looking over the shoulder of different experienced animators are really valuable.
Check out the site. Looks pretty cool with (among other cool stuff) a video interview with the one and only Ray Harryhausen. Also, one of the animation tutorials are available free of charge :)
