Netcraft toolbar API

If your business has anything to do with blogs or feeds you should make an effort to get your blog feed to work properly.
Not the case for Superfeedr. As of today the only thing in Superfeedr’s blog front page pointing for a feed is a sidebar link to an Atom feed and feed discovery is non-existent. Has this wasn’t enough you really have to be willing to read the sidebar to see this link. And the feed is not even valid XML.
I mean, Superfeedr works with feeds for a living, they should at least make an effort.
