Maybe because sometimes there are a mix of people using different software, and they really don't have much in common to discuss.  For instance, most of the time it is Poser people or others doing that type of images.  They usually don't find my Fractal stuff interesting.  Then again there are the Photography people, and possibly they aren't interested in the 3D stuff, etc.  I'm just taking a guess here. lol q-:
