The Evolution of Moe Among Otaku

Fascinating post on Cutfilm Tovent about Bamboo Blade, which raises the point that the anime blogosphere has evolved an understanding of moe. From early discussions of its definitions, to debates about its morality, to current comparisons of different moe elements, we're now all pretty comfortable with moe.

I get the feeling this isn't the first time this has happened; surely other concepts have seen similar debate and resolution. Outside of the anime blogosphere, outsourcing saw a similar trajectory: initial fear, followed by intense debate and clearly-drawn battle lines, followed by acceptance and understanding.

And wonderfully, this has led to understanding and more tools for thought. We can now talk about anime with more finesse and detail.

I wonder: what other aspects of anime remain to be defined?
