As the originator of this group, I've noticed that myself.
The purpose of this group is well beyond support, I trust there are other, better, dedicated places for such activity as StackOverflow and MSDN.
This group's purpose is to have a common ground for discussing concerns, ideas that are cross cutting wpf, silverlight, html5, and other UI oriented fields.
While I am not promoting support Q&A I am not moderating it for now.
When time comes where people are engaged in such discussions that those threads interfere with that I will.
I encourage you and everyone else, to put on the table thoughts, ideas so we will have something else to respond too :).
Thanks!
Ariel
