One of the most interesting mailing lists out there is run by Dave Farber. The list is called Interesting People. He’s a pretty smart guy and his list attracts really smart people. He posts about politics, current events, and anything interesting. He sometimes forwards some of the responses he gets from people on the list.
Anyway. I made a RSS feed of his mailing list for those who do not want to subscribe. Most feeds of his mailing list fetch only the subject and then link you to the page. This one fetches the entire post so it can sometimes take a second to load.
