Are QR Codes dead in 2011? Or is it just poor implementation?

Although huge in Japan, until recently a lot of us had no idea what QR codes were, until hdm did a post about them and put us all right.

(If you still have no idea, then have a look here).

But I will admit to being quite impressed with them and having seen appearing in different places can see quite a potential, but this doesn't seem to be shared by everyone. There have been some daft ideas, such as QR codes on underground station bill boards, with no mobile reception, or bill boards too high so the QR can't be read

Here's an interesting positive spin, and showcases some successful QR campaigns, as well as some of the less well thought out!
No, QR Codes Aren't Dead. They're Just Used Badly

Anyone else spotted any QR clunkers or want to share their own QR success story?
