Maybe it's the Halloween vibe in the air over the last few weeks, but here at HEALTHCARE DESIGN, we've noticed an odd trend of late. For some reason, several blog posts and feature stories dated a year ago (or more!) have been garnering fresh, new comments--and in some cases, some rather heated discussion. And while the nature of the Internet is all access, all the time, to everything, this is still a rather strange phenomenon, and one that we haven't really encountered before.

Check out these "undead" blogs and features that have seen new activity of late:

Whatever sinister (or perhaps downright spooky) reasons there might be for these topics to be given new life, we encourage you all to comment to your heart's content -- there is no time limit on healthy, active discussion. Please, folks, do keep it civil.
