As far as the Rouse's post though, he was basically saying the exact same thing you just said about his post, only about the post he replied to. The flow was roughly:
Guy1: Hey WotC is finally putting out non-randomized packs of minis!
Guy2: Who cares, I already have all the minis I need. Oh, and this is totally irrelevant, but I'll never buy a WotC book again either.
Rouse: Let's just stop making minis and books then, yeah?
All told, that's pretty much the least offensive reply I can imagine him making.
Exactly. Plus, it's very clear that his comment is sarcastic and humorous. Honestly, I'm appalled at how much people try to see confrontational subtext in others' posts. It's as if you want to provoke a confrontation. Learn to laugh a little.
But honestly, the reason this simple comment made such a wave is because of Rouse's position. I think some people only see WotC when they see him and think he speaks in an official manner everywhere he goes. The guy's not a machine you know, he comes here to relax, be informed, and maybe give out some info while he's here. It's called communicating with the fans with a human touch. And I happen to like it, especially the sarcasm. Keep it up Rouse!
