In regards to the poor grammar -- I've no doubt they prioritize posting speed in exchange for a more liberal writing style policy.
In regards to his grasp of tech -- I see nothing offensive about your example. He says it's probably a bug, and it was. I think his ability to grasp the implications of tech is pretty solid.

His ability to grasp tech is missing the instinct that sees those numbers (re: the Twitter UI "bug") and immediately thinks "Oh, duh, ordered-list tag is showing numbers when it shouldn't be. CSS file error. Happens a lot when I use Facebook and static files don't get loaded properly. Not worth writing about."
Not saying that means he shouldn't write, but as a webdev it's easy to see what's wrong with that article.
