This would only work if someone else made their radius cover the entire US and Canada. The way it works is that both parties have to be inside each others' radius. This prevents spamming and assures that if you're only interested in a very local scope, you only receive messages from people close to you. We'll try to make that more clear when we launch the beta. The screencast will help too.
