He's from Belgium, though I don't know where he learned English.

Probably at school, starting at the age of 11 something. Like everyone else at his age in Flanders.

Stupid Flanders.

Um, what's wrong with Flanders now? Learning a language is not trivial, and even less so if not via immersion as a child.

That was a Simpsons joke.

I'm laughing so hard right now.

Really? I mean really? No love for a laugh at a simpsons joke. wow.

How many languages do you know?

More than one, but I avoid blogging in them to avoid "you're bad at language $foo". Knowing more than one language doesn't mean that your errors aren't annoying.

English is a language, a tool for communication. What he wrote is perfectly understandable by any reasonably intelligent individual who is fluent in English. I'm sorry if his English proficiency is not up to your standards, but I assure you that it is far better than your Flemish, or French, or probably any other language than English, which happens to be the one you learned as a child.

So I guess it's a pattern in the PHP community to blog in languages you don't know. Almost like how they write code...
