StatusNet chooses the first content element in an Atom feed, while it should really choose the 'html' representation for its 'rendered' and 'text' representation for the (text-only) 'content'. GNU social will implement a better algorithm for retrieving Atom feeds, but that is yet to be done. So to avoid having link-less posts on remote nodes, we'll just do the old switch-a-roo. Other Atom readers, such as Mozilla Firefox, has the reverse priority (choosing the last of the content elements).
