Bruce Schneier's latest Friday Squid Blogging post is not a security story. It reports new research indicating that squid lived around the globe before the Cretaceous-Paleogene mass extinction event. That is the extent of the security-relevant content in the post itself.
As with previous squid posts, the entry serves as an open thread. Schneier writes that readers can use it to talk about security stories in the news that he hasn't covered, and he links to his blog moderation policy. The actual security substance, if any, lives in the comments rather than in the post.
For a security and privacy section, the source is notable only as a meta-example of how security experts create informal gathering points for unprocessed news. The squid research and the security discussion are unrelated; the connection is purely the format of the blog.
