Response to "MaintainableCSS"

@adambsilver recently published MaintainableCSS which aims to be a best-practices guide for writing CSS. It's a good read and gives generally sound advice.
I made a rather terse remark about it's similarity to BEM on twitter, and I'm hoping to clarify my thoughts in long form because I tend to be verbose and twitter isn't an appropriate medium for conveying nuanced thoughts. As this post is in response to MaintainableCSS, please be sure to go read it thoroughly before continuing otherwise much of this may not make sense.
