The blogger Alan Sullivan has died. This was not unexpected as he frequently blogged about his illness, but one wished him longer life. He was knowledgeable and opinionated on a surprisingly large range of topics. I enjoyed his political commentary, and his hurricane-season weather analyses stood out as exceptionally shrewd and helpful for those of us who live in affected areas. The discussion sections of his posts were lively and often gathered many comments, so he must have had a large readership. Alav hashalom.
