Some of the RSS feeds in the sidebar stopped working for mysterious reasons (DeLong, Krugman, Econbrowser, Calculated Risk, Free Exchange, Environmental Economics, and a few more) -- I didn't change a thing -- and several of you have emailed/left comments wondering what happened.
United decided to delay yet another flight (grrr!!!), and it gave me some unexpected time so I fixed them. For now anyway. Let me know if the feedes stop working again.
(TypePad has a limit on how many RSS feeds you can have in the sidebar, but I found a way around it -- that may be the problem, don't know.)
