The picture above was found on Flickr while I was scouting around looking for common license pics. It was one of the moments where you just pause and go "hmmm!" - where a picture seems to encapsulate a lot of the things you've been wondering about lately (and for me in this case it included things like teaching approaches, online learning, blended learning, DOGME ELT, you name it).
The original source is here on Flickr, and it has a nice caption to it. Worth a look and a quick read. Nothing too deep, but a nice escape from the more shallow diversions of our "trade".
