This blog has been inundated with a huge traffic increase for the past two days - certainly a very welcome phenomenon, but an unusual one. Virtually all the new traffic comes from “StumbleUpon” - a Web service that feeds random Web pages matching selection criteria that you choose (it lets you “stumble upon” pages that refer to things you’re interested in). Somehow, this page is coming up a whole lot for StumbleUpon users, though, if anything, even less than usual for all the other readers.

So, first of all, of course - Welcome, Stumblers! Thanks for dropping by! (Though I see you share the universal aversion to leaving comments.) Please come back often.

However, I’m a little puzzled. Does anybody know why this page is getting so much StumbleUpon traffic suddenly? Is it a fluke, or are there a lot of users who are interested in bioethics? Am I doing something right that I should keep doing?

As always, feedback, comments, and visits are much welcomed.
