At the risk of turning the blog into an ersatz RSS feed for my Ars stuff …

Actually, I kind of like that. I don’t see a way to subscribe to your posts only on Ars, and, while I might like to read everything on Ars, it’s just not practical at this point. You used to put up a post (here) every week or so with links to your Ars posts for the week, and I liked that. Assuming it’s not too tedious for you, I’d appreciate if you’d start doing that again.

Fantastic article! Thank you! This kind of rigorous fact-checking is incredibly useful for the conversations that the Open Education movement (for example the Open Courseware Consortium) is having about opening up education. The culture of fear and worry that is created by repeating these numbers over and over, hampers our efforts to promote the use of “open licenses” for educational materials – even though many of the open licenses we promote do not prevent commercial activity.

I also found the one paragraph summary of the Economics (on the last page) very accessible, and will be pointing others to it.

Best, P
