digital photography online course and blended teachers’ PD

was reminded by fb feed of Professor Marc Levoy’s Digital Photography google site, could this be a next step for creating a variant to the online component in our blended learning courses?

first, an instructor (teacher educator) would make his/her contents freely online. teachers would be free (in terms of will) to browse and learn from the contents/videos freely (in terms of time and cost).
second, an instructor would conduct a blended Clinic course(s). teachers who perused the contents, and would like to deepen the learning through face-to-face engagement can sign up for the Clinic. during the f2f-online-f2f-online-f2f… cycle, the google site can become part of the resources upon which the conversations are anchored upon. likewise, in the blended Studio course(s), the google site can serve the same purpose as conversations are steered to incorporate the practice component.

just a 联想 (:
