I actually have found QR codes to be effective when used in presentations at tech conferences. At the end of each talk, I have a QR code on the final slide that points to a page where attendees can get more info.
About 1/4 of all people who visited that page at my SXSW talk this year came in through a QR code. This is kind of an anomaly because a SXSW talk is probably the perfect place to use a QR code.
My one complaint is, of course, that they are hideous. It would be nice if there were a central database where you could upload your own symbols and assign them to URLs.
