The article looks for me like a pile of words.

"This is because, unlike Python, for instance, Perl is pretty sensitive to implementations and every operator should be in the right place to have a relatively efficient program." - what do you mean? I've read it thrice and could not get it.

"Because PHP has a gradual learning curve and cheap to host, it takes damages in terms of performance." - again WHAT? Learning curve and performance are not interconnected at all.

I'm afraid to read more of your articles. Really.
