That's unfortunate.
However in practice the copyright is rarely, if ever, enforced for ordinary blog posts written by a pseudonymous author. If hypothetically somebody for whatever reasons violate the copyright, it would be technically illegal, but the copyright violator could be sure that nothing happens because I have no incentives to sue anyone. If, on the other hand, my text were part of some company's business plan, the incentives to sue violators would exist. Therefore the present situation is preferable to me.
But anyway, if it can be done this way, I hereby declare that all my past, present and future writing on LW are in public domain.
There is a very knowledgeable man named Mark S. Miller who puts, "Text by me above is hereby placed in the public domain," at the bottom of his posts. He's been doing it since 2002.
(He only posts on mailing lists, though, AFAICT, where of course it is accepted practice for static text to appear at the bottom of posts.)
If you've been following the announced partnership between LessWrong and Castify, you'll know that we would like to start offering the promoted posts as a podcast.
So far, everything offered by Castify is authored by Eliezer Yudkowsky who gave permission to have his content used. Because promoted posts can be written by those who haven't explicitly given us permission, we're reluctant to offer them without first working through the licensing issues with the community.
What we propose is that all content on the site be subject to the Creative Commons license which would allow content posted to LessWrong to be used for commercial use as long as the work is given proper attribution.
LessWrong management and Castify want feedback from the community before moving forward. Thoughts?
Edit: EricHerboso was kind enough to start a poll in the comments here.
