I have seen grammar and spelling comments given in the spirit of helpfulness, but this was not one of them, and adds nothing.
My comment adds very little more than that, but I'd like to remind people that many very smart engineers and business workers have a terrible grasp of formal English, yet they get the job done and more. WalterBright's comment was short, but pointed to more information, and was a potentially useful comment. The discussion should be about the content of his comment.
The fact that he used the wrong word is virtually irrelevant, we all knew what he meant. Yes, if you have a strong grasp of formal English you do make yourself seem more credible, especially in a formal context. But it's not the thing to focus on. Not here.
S/N on HN is amazingly high, but it is still a casual forum, and we should all cut each other generous slack.
Written with helpful intention. :)
