She wrote a blog post, put it online for ... who knows? It could be literally any reason. For her own later reference, to help crystallize her thoughts, or just for fun.

Again, I thought the piece was informative. I figured I'd voice my opinion in the form of suggestions, since this is a forum for such things.
Lesson learned. The only feedback one can give is positive.
>dudes, always dudes
