I don't know of any magazines out there, as AE is a very niche, specialized market. (vs something like photoshop, which is used by a range as wide as seasoned pros to soccer moms hacking up their point n' shoot photos).
Creativecow.com is one big AE resources. Note I didn't say design resource. You won't find that there, but as far as nuts & bolts on how to work the proggy, there are many tutorials.
Thanks Kai -- that could be useful. I used creativecow when I was getting into Final Cut, but now that I am using AE, it could be a lot of help.
It just seems like it's hard to find current, "stylish," "modern" information on AE/motion graphics design in general. I might be looking in all the wrong places, or I might be asking too much to begin with -- if there were freely available tutorials on how to make the latest commercials, everyone would be doing it!
