No intention of slighting any software, I assure you.

Blender is undergoing almost constant and rigorous program development, so it's incredibly robust and powerful. Because of that, the documentation can get out of date more quickly than some other programs. It is an excellent tool, and an amazing success story in the world of open source software.

And of course, as mentioned, the best resources (for all software, really) are support forums and web sites where you can talk with other users of the tools.
