If nothing else, check out his excellent lists of aggregated links, which include brief commentary. Frankly, I often enjoy them even more than reddit, since they're the product of deliberate curation. Seliger is a generalist, with thoughtful insights on a broad number of issues, including sex, economics, startups, technology, academia, and education.
My medical friends also highly recommend his post on whether or not you should become a doctor.
