Great to see a recent XKCD comic contribute in its own wonderful way to the efforts to raise typographic awareness and make more people realize that fonts need to be used appropriately: Papyrus is the new Comic Sans!

I must admit I also twitch when I see Matura MT Script in signs and documents... Ouch, painful!

So please, don't kill your message with a inappropriate font when they are great open fonts out there to choose from which may fit the connotation of your text much better. Spend a little more quality time with your font menu to choose something better...
