That might change soonThere's a huge disconnect with owning the system and reading about it. Especially when much of its best features are qualitative and not quantitative. I can compare RAM speed and know one is better, I can't exactly do the same for games let alone exclusive ones. Also when people compare features they do it for ones that already exist (How much is this like LIVE?), for ones that don't exist elsewhere (Miiverse) it's hard to understand why you want or need it until you actually have it.
And of course demographics. Miiverse is 100% people with the console so obviously there's more positivity since these are the people who decided to spend $300 on the new Nintendo console and play it before everyone else. The topics are all Nintendo topics. You won't see console wars at all.
Unless nintendo mods ban every post involving the competition
