Oh, I've seen Poser animations / stills used often: primarily on television shows and in TV advertising.  Yes -- if Poser gets the job done quickly & cheaply: then it's a plus.  No, Lucas or Pixar aren't likely to produce any feature-length movies using Poser -- but I'd still say that a common television / magazine / print presence makes a software package worthy of a "professional" label -- at least when the software is being put to what are clearly professional uses.

As for the use of Poser instantly translating into a lack of "artistic integrity" -- there are those to whom the very term "computer art" itself is an oxymoron (I like that word......it sounds so.......sophisticated........).  If it wasn't done with canvas & oil paint -- then it ain't ART.  Even if it was produced in a $35,000 program on a $250,000 workstation.  Or at least that's the thinking of some...........
