I actually noticed only two grammar errors while reading the article, even though I read the article after reading your comment. Now when I go back and look at the article again I see more errors, but since I (a native English speaker) didn't notice them when I read the article for real, they weren't a problem in this case. I've read articles that I started hating because of all the English errors, but this article doesn't even come close to that level for me. I don't think this article deserves such a long rebuke for bad grammar when I had so few problems reading it.

I see this kind of comment frequently, and I must admit sometimes I feel that way too. But if you notice the status bar on the iPhone screen shots, you will see "TELIA" which seems to be a Swedish cell provider. This means that English is probably not the author's native language, and should a) give him a break and b) commend him on a technically awesome article in a language other than his own (as a bi-lingual speaker myself, I can tell you I'm really impressed).

Are you fucking serious? First of all, the guy is Swedish. Second of all, he made like two mistakes.

If he made so many mistakes the meaning of the post was lost, maybe your pedantry would be relevant. However, in this case, all you've done is wasted everyone's time and now we're discussing minute grammatical points in a writing-unrelated post.

And I thought I was a grammar Nazi.

So, where do you get the impression that the author wants to be taken seriously by people who are easily offended?

This looks to me like a typical personal blog where a non-native speaker jotted down his notes about a certain topic. The text is perfectly understandable and the grammar mistakes are harmless. Take it or leave it.

I don't see anything in the GP about being offended. And I totally agree; I automatically and almost unconsciously take an article less seriously if it's got glaring and common errors.

I also disagree with your characterization of the amount of work that went into the blog post. From the number of screenshot examples and the overall structure of the piece, it looks to me like the result of a significant amount of work.

That said, direct feedback (like through the links provided at the bottom of the article) is probably a better way to let the author know about (and correct) the mistakes than a comment on HN.

I like Stephen Fry's take on grammar and 'correctness':

I think it's particularly rude to criticize a non-native speaker for their lack of proficiency in the non-native tongue, outside of fora where proficiency is to be expected (e.g. translation, creative writing, literary criticism).

To my mind, it also shows an insular anglosphere-centric perspective, one to be avoided.

Was the linked codinghorror article intended to be an example of a well-written, proofread article? It took a glance for me to see "that that" in the third paragraph.
