I've come up with yet another million dollar idea that I'm going to give away, and it came to me this morning while reading the Journal of Nuclear Medicine.
I still like paper journals. They are pretty easy to manipulate and they don't take batteries. And I grew up reading them. And we're all familiar with them, and so on.
But periodically (pun intended) I run across an article I'd like to share. Then we have to go through the joy of searching for the article online and sending the link, or if I'm really feeling stubborn that day, I might just photocopy the paper article onto more paper!
So, here's the idea, it's simple and costs nothing. At the footer of every scholarly article, and maybe just any article, let's place a copy of the QR code! Then, if I want to let my colleagues know about the latest in defecography, all I need do is scan the code and email it or whatever! What a simple way to disseminate information. Did I mention this won't cost anything?
I'm giving this idea away, but if anyone wants to pay me for it, I'll graciously accept. By the way, here is the code to this blog post in particular:
