PHP has a bit of a reputation for attracting unskilled programmers, but that's because it is so easy to get started with, which leads to a lot of newbies writing it. All that means is that you may have to filter your candidates more carefully when you hire, and nothing to do with the language itself.
In short, the post seems subjective and opinionated, without showing any concrete problems that they overcame with alternative languages or frameworks. "Codeigniter is bloated" vs "Paraglide is awesome" are both so vague as to be useless. "Ruby's syntax sucks" is even worse.
Much better to have had a list of specific things that dissuaded them from using one framework or language, and some killer features that convinced them to use the other - if all I see is a personal opinion without any reasoning behind it, I cannot make any useful decisions in my own situation.
