Do they Teach Grammar in Canada?

I just read the introductory paragraph to what could have been an interesting article regarding Ubuntu and TeamSpeak 2. Unfortunately, that's as far as I got before I ran into the first mind-numbingly obvious 4th-grade grammar mistake. I took a breath and started again. I made it two words before the next mistake. Then almost a sentence.

The article's author uses combinations such as "the like", so one may assume the writer is over 8. Judging from the rampant problems with the piece, however, I would have placed the writer as a young, mentally-challenged male from a rural part of America where schooling follows more functional goals and students split schooling with, say, field work.

Perhaps I'm misjudging the author, but unfortunately 'he' leaves me little to go with. Maybe after he takes one damned second and proofs the piece, it may look better. Hmm, proofing stuff that's important: what a novel concept. I'd do that here, but, then again, nothing here is important, is it?

Let this be a lesson to you: Stay in school, kids, or you'll end up a busker like this guy.
