I usually only do post work on projects that I consider truly serious endeavors or for added effects that you can't get from Poser. Most of the images that I've posted on this site the by line is the only post. This is because I use this site as a way to work out my skills and to get knowledgeable opinions on how to improve them. If I masked the image with too much post members who critic my work wouldn't be able to give me honest opinions on what I need to work on. But this is just my preference, if you're goal to comming here is something different then you're workflow can be what ever makes you happy. 

On the other hand I've seen several images on here that are in the Poser galleries that probably should be in the photoshop galleries. The work that they've done in Poser was beginner at best, but their post was outstanding elevating the work to a new level, but it would be like me working out a texture for Viki in Photoshop, rendering it in Poser and then posting in a photoshop gallery for opinions.  

Ultimately I'd say post for the sake of post is just as bad as no post for the sake of purity IMHO.
