Hehe, yeah, I know "that guy". And you're right, he's a douche. I can totally see your point, but you just gotta keep scrolling man. I mean, c'mon, you got all CAPS LOCK angry about someone sounding off about how they think the iPad sucks. It works both ways, try starting a thread round here that critically assesses the iPad and in seconds you'll have an army of fanboy nazis doing the exact same thing that annoys you so much.
And as for conversational standards; on this new-fangled and "magical" interweb, "conversational standards" don't apply as they would in the real world. Most threads on most forums have multiple conversations going on, I tend to scroll through to the ones I'm following. It's no big hassle, in fact it's expected. No need to get so worked up!
