Just for the record, Philip Greenspun is many things, but Harvard professor is not among them (he's simply using a blog service run by the Berkman Center at Harvard Law School, which you can find out about by, as per the article, "hacking" his blog's URL: http://blogs.law.harvard.edu/ ).

Anyway, while not a Harvard professor, "philg" is a very interesting guy who has done a bunch of worthwhile things (e.g. "Philip and Alex's Guide to Web Publishing", htttp://photo.net, Ars Digita, etc.) that should be of interest to Hacker News readers. He writes well--in books, essays and blog posts--and he writes provocatively, with a mix of snark and self-deprecating humor that many enjoy.

In short, he's worth knowing about in my view (and I'm happy to know him). For links to his past and present projects: http://philip.greenspun.com For background info: http://en.wikipedia.org/wiki/Philip_Greenspun

P.S. As many readers here already know, he's also the author of "Greenspun's tenth rule of programming" (which led to the term "Greenspunning"): http://en.wikipedia.org/wiki/Greenspunning
