When I wrote the guidelines, it really was all about, "be consistent". camelCase is my preference, but really, go with what makes sense and is least disruptive.

I actually REALLY like SuitCSS' recommendation and I definitely wouldn't object to it.

I intentionally didn't address project architecture (folder names, file names) because ... to be honest... I still haven't quite figured that out.

But I'm going to think on it and maybe add something to the guidelines that echos your suggestion.
