I dislike being cynical, but I don't see many posts by Snoop that aren't in an article without his name in the title... or that aren't promoting one of his products. I'm smelling good PR work here, not an authentic interest in reddit.
It is depressingly rare nowadays to see AMAs of celebrities that are not purely for advertising $upcomingthing and low on content.
I haven't looked too deep in that sub, but maybe there are some going on that just don't make the front page? There are some weird ones occasionally, mostly people who've had some sort of surgery or health problem, from what I've seen. But really, can we just focus on Rampart?
