I have spent the late afternoon looking at ThingLink.
I have uploaded an image of Donald Bradman onto my ThingLink page.
I am working on each image in WordPress becoming a ThinkLink. For the moment, if you visit the Donald Bradman picture at this link you should see three icons when you hover over the picture. (I have uploaded the PlugIn for ThingLink for a self-hosted WordPress blog so you should see the effect here too.)
I think this is an outstanding innovation and has the potential to transform how we share and build information.
This image is editable by anyone under the current settings of the image.
