Signatures are silly. They're hard to verify, and easy to forge. And my own personal signature has degraded over the years; I can write my autograph twice, and although they both look to me like my signature, they no longer look like the same signature.

So I can understand why nobody any longer wants to have to verify signatures.

Most people that ask me for a signature (usually deliverymen) don't care what I scrawl on their device; it's usually not even an attempt at a signature, it's just the simplest <squiggle> I can manage on those awful devices.
