Quiet as far as WE know, right? In reality, they could be posting on the blog, but might be getting blocked for whatever reason. And they really can't come over here and post (assuming they've heard of WS) can they? I mean, they CAN, but but they can't introduce any new facts without getting verified, which could be very intimidating.
And if they really know anything about a stalker, a murder or M's (possible, but not not proven) drug use they might be afraid to come forward for fear of being "outed." I wouldn't want to live in fear of the wrath of the (alleged) perp(s) or conversely, take any backlash for saying something about M that might be upsetting to hear if such info exists. After all, mom posted on her blog that she knows how to look into IP addresses now, and even suggested we sleuth each other over here at one point.
Another possible reality is that they aren't being quiet, but are communicating in ways/places we don't know about or can't discuss here.
JMO!!!
