All Xangas have been delisted at Planet Xavier, because their archaic RSS 0.91 feeds don’t properly provide the date of publication, so the feeds always stay on top, polluting the page with entries from a year back in some cases.
I’ll be working on a bugfix ASAP. This is an opportunity for me to learn a decent amount of Python.
All LiveJournals, Blogger blogs, and independent blogs (like this one) will remain syndicated as before.
Oh, and, a kind note to those still using the horrible Xanga service: please do switch. Xanga uses laughably-antiquated software, and the only thing to the service’s credit is that they are still up and running at all. I highly recommend Blogger, which allows you to completely customize your site anyhow.
