I've gotten over 20 emails in response to my Fighting Spam with Spam column since it was posted to the web last Friday. And that's just the mail directed at my own mail address–the “sound off” link generates mail to the magazine's letters mailbox. This is the most mail I've ever seen on a column–undoubtedly, it's because spam is just one of those subjects that touches everyone.

A personal aside: I don't necessarily think that David Black's idea would make any difference, even if it is technically feasible. It could create as many problems as it solves; it's sort of like trundling out nuclear artillery to deal with a shoplifting problem. Sure, nobody will be shoplifting anymore, but then again, nobody would be able to make money legitimately in the market anymore either once the fallout settles.
