"September 2014, almost 20 years after the inital Poser release, and there is NO single error free and end user friendly figure.

That is not bashing, that is the reality."

No bashing here, but what I don't understand is why any figure manages to get a release with errors in it in the first place.  It's just a mesh, and there are tools to check for holes, reversed normals, unused vertices, perfect symmetry etc.

All it takes is an ounce of pride in your work and to have the enthusiasm to check all of those things before you release it to others.  It's not rocket science and the tools do the work for you.  Go through it in a logical manner, do it right.  If a program is responsible for messing-up a mesh, that's differen't, but I don't think there's any excuse for the figure-mesh itself having errors in it.
