I never filter my browsing by tool (Poser, Vue, whatever). I dont think it's relevant at all where the image was prepared or rendered. Anyway, nowadays most of the really interesting stuff is made in various tools. If you filter by Poser, for example, you would miss some fantastic creations by Stonemason, for example, or Hobbit, or DOM1 or Petemohr or... 
In many of my images, I use Poser, Zbrush, Vue and Photoshop. Where should I post it? In the tool that I spent more time on? In the tool where I rendered? I dont think it really matters. The tool is secondary, IMHO.

So, normally, I click on "what's new" and browse. Occasionally, I filter by genre (mainly to avoid "portraits" and "people" genres because these tend to be EXTREMELY repetive and uninteresting, as Stormchaser mentioned. In most cases, I even seriously doubt it can be classified as art... But that's a different discussion altogether... :-)
