So my understanding was: * This simply made sense for books, since you can't update a book that's already out there, just release a new version. * Web pages were similar, mainly because people wouldn't update them rather than couldn't update them. * But then came blogs and other dynamic content, which did get updated. So you'd want the copyright date to match the most recent post, not the creation of the blog/site. This means updating every year for any that are still active. * Other sites that don't update as often then copied "make sure it's the current year" without really thinking about it. ...and that third point doesn't contradict this post. You want it to match "first publication" of the most recent post, right? (assuming you include year at all)
