There are, perhaps, a hand full of users that post animation on youtube, since I don't animate myself, I can't refer you. However, the animation is not restricted to just creating video content, we can use animation to dress models better with dynamic clothing, create dynamic hair, or generate better pose from several static poses. But the animation aspect can be tedious and the workflow intensive.

Generation 4 models, by far, still the most popular figures created by DAZ 3D compatible in both DS and Poser. Easily identified as Victoria 4, Michael 4, Aiko 4, She-Freak 4, The Freak 4, The Girl 4, Stephanie 4, The Kids 4, etc. They are all tagged with a 4 on the end of their names and content created for them is usually depicted in the descriptions. Thank goodness DS has kept the format interpretation of Poser files so that content can be read in both software. All the base models can be found at DAZ 3D, but I wouldn't go quickly to their site for immediate purchase. Once in a while, those models and morph packages appear in their free section for about a week or two. Wellworth picking them up then if you are patient to wait. Loads of content everywhere.
