I can see from my server logs that a bunch of people have already found these, so I figured I’d let the rest of you know as well. The most recent kottke.org posts are available in two flavors of RSS: RSS 0.91 and RSS 1.0.
What do you do with these files? Well, you find yourself an RSS reader and point it to one or the other of those files. Some programs and services that you can use to read RSS feeds include NetNewsWire, AmphetaDesk, Aggie, SlashDock, Radio Userland, NewsIsFree, and Peerkat. Good luck.
