A while back I went to the OER annotation summit where I learnt about hypothes.is, a tool for adding a layer of annotation on top of the web. If the idea of annotating the web sounds like one of those great ideas that has been tried a dozen times before and never worked, then you’re right and (importantly) the hypothes.is team know about it. It’s also one of the great ideas that is worth trying over and again because of its potential. Today I took a quick look at how they’re getting on, and it looks good.
