> Why aren't Identicons or QR codes used more?

Nothing stops you from turning that hash into a QR code (afaik Antox does) - but then how do you copy & paste it?

a common usage, if you're able to do in person meetings, is to produce and scan them with your smartphone. much better than spelling the whole fingerprint. this makes, for instance, gpg key exchange a nice thing finally.
