This is a cool idea--can we have people who specifically use sign language for regular communication identify that in your posts? I'm all for interest in the topic from outside the signing community, but the opinions of people who rely on sign language for actual communication are much more important than just what a general audience thinks is fun or neat.
Agreed. It would be great if we could get a native sign language speaker from the community to make a pick.
I'm guessing getting it accepted as a real sign by the standard organisations in different countries will be a bridge to far as long as Bitcoin is not mainstream.
