I think a large part of the problem is that there is a Poser specific paradox.  It's not just the amount of free and commercial content that people are tempted to use, but also that it's always taken some kind of black magic to get things properly into Poser.  I used Caligari (predecessor to TrueSpace) for years to make mecha (giant robots), vehicles, buildings etc.  The one thing I couldn't do easily in it was to model figures as there were no bones, morphs etc.  When I bought Poser I had ideas of using Poser figures sparingly in the background to add a new element to my work.  I couldn't (and still can't) believe how difficult it was to get even simple props to work right.  It took ages for me to discover that the obj format was the most neutral among my various tools and even after learning UV mapping I still had the problem of Poser trying to smooth all of my objects' hard edges.  I've since learned more about object import/export settings, preserving my groups, and even a little rigging.  I don't want to use a text editor or some strangely named utility to hack together a figure, nor would I imagine anyone would who was drawn to Poser for it's famed "ease of use".  I'm surprised that I can't think of one single program, from Anim8or to zBrush, that a person can use to create a Poser ready figure without ever touching Poser, its various related utilities, or an existing premade figure.  Anyone?
