George recently wrote and released:
…a Greasemonkey user script that will find those hCalendar events and provide a link to import them into any calendar program that supports the iCalendar format… any time you see an event on the web that has hCalendar information, you can click a link and it’ll be added to your calendar so you don’t have to copy the information by hand.
Nicely done George. Next up, who is going to write a Greasemonkey user script (or extend George’s) to detect hCards and provide links to import them into any address book program that supports the vCard format?
Update: George himself has written it. See his updated blogpost to get it.
