So I thought it was pretty impressive when Jay Cross posted a list of 195 posts about MOOCs yesterday. Authoritative. Then I got to thinking, did some checking, and realized that I have personally authored 453 posts about MOOCs. This link is to that page, and I've set it to automatically update weekly, so there will always be a current list. Meanwhile, I went over to mooc.ca and found that since last July that site had aggregated 3708 posts about MOOCs. So I think between the two sites we've got the topic pretty much covered.
