since google reader (which accounts for the majority of our subscribers) and potentially many other readers don't support multiple author elements in atom feeds, and it's a really bad thing to have the wrong author displayed, let's remove the <entry><author> elements from the reader feed.
my understanding is that it's okay for an <entry> to lack an <author> element so long as there is a <feed><author> element.
we've discussed in #332 the concept of having two feeds - one for readers, and one with extra info that we can use to build alerts, google scholar feeds, etc.
[PLoSRESTDevGuide] refers to a representation parameter that would let you choose between different representations.
In keeping with that, we're asking for the <entry><author> element to be removed from the public representation of the feed, but left in the internal representation (along with extras like volume, issue, citations, etc.)
this is a replacement for #477
thanks!
