I guess I don't get it. If somebody shows me information I can't read with my own eyeballs, I have to really care to take the time to read it with a device. When the novelty has worn off, I'm not going to keep beeping my phone at every code in sight. Especially if they mainly turn out to be URLs I could have read in plain English and/or advertisements.
Is this actually useful, beyond the fad's lifespan?
