I left this comment on an article over at Forbes.com
This is an interesting article, but seriously, Forbes, is anyone there watching over the grammar? Is the third most innovative company America? I don’t think that’s what you meant, but that’s what you said. Maybe I can forgive the missing hyphen (well, no, I can’t, not from alleged professionals) in the Red Hat bit, but there’s some nasty comma action going on.
Later, another missing hyphen, that changes the meaning of the sentence.
Probably the most annoying error is the comma splice in the da Vinci section. Good Lord, people, learn to use a semicolon! You’re Forbes, right? Professionals and masters of prose? Certainly no one would confuse your articles with some unchecked blather steaming out of the blogosphere. Although you’ve done nothing to differentiate yourselves in this article.
Show a little pride in your work.
Just because it’s the Web doesn’t mean you can write like shit.
