One of the founders of Twitter was tweeted this photo from Cardinals ball player Jason Motte. That signature - it's not in ink. It's electronic. Meet the egraph, which may take over the 'old fashioned' hand-written autograph.
Let's say your favorite musician sent you a personalized egraph. Would it be as cool as having them give you an autograph?
(Of course, you're more likely to get a signature via the internet and should be happy to have anything at all).
