OKAY, so RSS should now be fixed for just about everyone. If you are using feedly, you may have issues due to caching. We're hoping this wears off as of today, but it's possible it'll linger a little longer. Please just keep us on your RSS feed for a bit, and it should go back to normal.
Sorry for the trouble, but it looks like we're over the hump. Thanks to everyone who sent bug reports.
Also, here's a preview of things to come.
Hey geeks! We're still getting reports of RSS bugs. If you're not getting the comic in RSS, please let us know your software and (if possible) send a screencap. Sorry for the trouble!
Sorry about the RSS bug. Should be fixed now.
