quote from alt.html today:
Yep, my first thought was “how do you use a radio button on paper”?

My second thought was that in J.K. Rowling’s world, parchment with form controls and dynamic display is probably rather commonplace. This led to the third thought, which was to wonder if the _Daily Prophet_ and the _Quibbler_ have pop-up ads, and whether there are spells to block them. Which led to the fourth thought, which was to wonder if such publications ever tell their readers that they need to “upgrade” their wands in order to read them; “This scroll requires an Ollivander’s wand, but you don’t have one.”
