I think it might be worth looking into. Not every past post that Cory highlights on his Tumblr gets a repeat thread here on the BBS, but quite a few of them do. And looking at the pattern of events the Tumblr post always comes after the repeat BBS thread which would make sense if Cory is placing these old links in his Tumblr queue to post later.

July 30 - Flowchart shows the complexity of the New Zealand’s Internet Disconnection copyright law
If I’m right, by Tuesday we should see Three-hole punch debut, April 1940 and New Zealand wants a Ministry of DRM show up on Cory’s Tumblr.
Edit: So Cory’s going to be at Burning Man until Sept. 5th. and supposedly off the grid. Another test to my hypothesis - do any repeat threads show up on the BBS during Cory’s absence?
