What's the convention on making a top level post to link to something vs posting in the open thread?
The most recent top level post for linking was TED Talks: Daniel Kahneman and that one at least had a paragraph worth of non-link material. Other links with comparable thematic relevance have been posted in the open threads.
Unless you have nothing better to do with your time, after the first few days the open threads are so full of stuff that they are not worth wading through. That's one reason I don't even bother posting my short ideas or questions; if I don't bother to read the thread, why should I think anybody else is going to read it and and post a worthwhile comment on anything I might post on the thread.
This article is worth reading, updating based on the evidence if appropriate, and then discussing if you have something to say.
