I would assume the down votes are because this doesn’t really add to the discussion at all. If you spot typos why not notify the original website instead?

That's what I hoped to do with the original comment. I didn't want to send them an email for something this trivial and I was just leaving the comment in case anyone from Anandtech stumbled upon it. The typo is not really an issue and my comment was not a criticism. I was just trying to be helpful but I can see how that can appear to be when my comment is just about the typo and not the content of the post.

Honestly I don't mind. I was not commenting on the quality of the post, neither was the typo that much of an issue. I have seen people from Anandtech active in the hackernews and I just this is a good way of reaching them and letting them know something trivial with their posts.
