I recently attended a talk on the Open Badge Framework, by Grainne Hamilton, from the JISC Regional Support Centre Scotland. It got me thinking about the potential Open Badges has a way to allow people to reward sites for a high level of accessibility.
The post that follows is a direct copy of what I originally published on the University of Dundee’s eAccessibility blog. Have a read and let me know what you think.

A recent exchange on Twitter has motivated me to write about the contribution published surveys on web site accessibility make towards understanding and addressing the problems that hold back web accessibility. I’ve read, and continue to read, many, many papers presenting the results of surveys of web sites, and I think we need surveys to look beyond just the data and instead delve more deeply into why the results are as they are.
