Some time ago I set up alerts through Google that feed into my RSS reader. This service searches for mentions of The Web-Footed Booklady and bookminder online. Most of the alerts that filter through are for mentions I already know about such as Twitter comments but occasionally an alert will lead me to a new contact or some great resources.
Today an alert led me to @auntytech 's delicious page because she had bookmarked my post from yesterday. Browsing through her other bookmarks I came across some useful QR code resources I didn't know about. Like the 1 Tool at a Time: Build Your Own Toolbelt wiki which just happened to have an archived Elluminate webinar on using QR Codes along with the Slideshare used in the presentation and a list of links to other resources. Thanks, Donna!
