Minion Comics recently updated, and split their site into several new ones. The new RSS feeds for each individual comic give the “This address does not point to an RSS feed or a website with an RSS feed” error when I try to add them to NewsBlur.
The rss feeds are located at the following urls:
http://www.cargocultcomic.com/rss.php
http://www.powerwentout.com/rss.php
http://www.wizardschoolcomic.com/rss.php
These are part of the same set of sites, and also don’t work, but they are unlikely to update anymore anyway. I’m adding them here just in case they are helpful in diagnosing the problem.
