just a quick note to say i see SM people here in the forums all the time.  iirc, just yesterday or so i saw efstarlet tell someone how to contact a staff member directly for help with technical problem. and most threads about Poser in general i've seen that haven't been simple kvetch fests (like this one- to be clearer, this one is an example of a thread that isn't just a kvetching thread) have had an SM employee in them.  Stefan pops into a threads on render optimization and materials every now and then (which i've seen as a bagginsbill follower), and i've seen Teyon ask about what people want in terms of figures quite frequently. 

otoh, i only see DAZ people here if they want to do damage control, but that's kind of to be expected.  it would be kind of discourteous for them to have a strong presence at a competitor's site.
