Twurdy has been created to provide people with access to search results that suit their own readability level. Twurdy uses text analysis software to "read" each page before it is displayed in the results. Then Twurdy gives each page a readability level. Twurdy then shows the readability level of the page along with a color coded system to help users determine how easy the page will be to understand.
Interesting post from a prolific Ed blogger who has always written about Ed and the "bleeding edge" worth following and very readable.

I particularly like this position because it takes into account the longevity of the teachers capacity not only to with stand the change but also to be part of the new paradigm.
