Hey,

BlenderNewbies has a great toolbar for download that has RSS feeds to most of the major Blender related sites. Recently they added an RSS feed to the toolbar for Animation Tips and Tricks that should help you search out information more quickly than asking here.

Here's the link to the page where you can DL the toolbar:

Sorry I can't be more help but I don't animate in Blender yet.
