QR code note taking

I can’t decide if this is lazy, or the exactly opposite: Instead of writing down a long URL on a sticky note so that I could carry it with me, I dropped it into bity.ly, added .qr to the end of the shortened URL, which handily generates a QR code, and then printed out the QR code so that I could simply scan it to retrieve the URL instead of having to type it in on my iPhone.
