One of the tags at the end of the post is "LinkedIn". Could be a red herring, but that would be my guess (seeing as his post doesn't otherwise refer to them).
There's a fogus on reddit, posting a lot of alternative os articles besides pointers to blog.fogus.me, if it really is Michael Fogus, then I hope his next project will involve os design (kernel and user), especially since he mention AI, wouldn't it be nice to have a little bit of prolog inference in our daily routines ?
Well, he does imply that he'll neither leave the Clojure community nor stop blogging, so I'm keeping my hopes up. Besides, whether they are Clojure-related or not, his blog posts are almost always interesting.
