Minor edits for style and readability that attempt to retain the author's voice and intention.

I like the blog post. Especially the "Well, no" part. The overall direction and tone, I like. Short and sweet is good, too. 

Still, I worry that people won't understand it. The masking concept at its core is so simple, readers may shrug it off as no big deal.

Perhaps I will try a more aggressive edit to the content itself to see if I can suggest something.
