PUMA Open Thread

Atdleft posted his piece on HOUND vs PUMA at Taylor Marsh's Hot Topics Diaries page and I noticed the following response that is certainly worth some discussion:

The fact that HOUND was created shows that PUMA is no fringe group like people try and downplay it as...but an actual movement.

Otherwise why create another acronym based group to combat it if it's nothing?

So what do you think? Do we take this movement seriously? Most of the Obama people I've encountered don't seem to be worried. I've been labeled a "concern troll" for pushing back against words like "dead-ender."
