The #blimage challenge was started as a bit of fun between Amy Burvall and I. We started it on July 18th and it has been growing steadily ever since with many of our friends and colleagues participating. The challenge is this: Send an image to friends in your personal learning network and ask them to write a learning related blog post about it. They then challenge their friends with an image of their choice. All the posts are labelled with the hashtag #blimage (blog-image) so they can be easily discovered and aggregated. Since the start of activities, the following posts and other artefacts related to #blimage have been posted. Several are destined to become classics of educational blogging.
