Dear author: Please stop misusing 'less'. It should be _fewer_ disks, _fewer_ books. Fewer is for discrete things, less is for continuous. As in: fewer dollars, less money. http://en.wikipedia.org/wiki/Fewer/less
I'm OK with polite corrections that address writing that canonically lives here -- especially when it can result in a quick correction to the original headline/comment. (Even so, I would love to see software support for friendly proofreading comments that don't clutter the main thread -- for example visible only to the author, or appearing in a separate 'meta' view, or which expire when the revision-window of the target expires. Then we can get the benefit of many-eyes-improved writing without lingering proofreading noise.)
