Since feed url is the URI for the user, redirect to the user’s profile page This is also our view for a particular feed

 
      format.html do
        if feed.local?

Redirect to the local profile page

 
          redirect_to user_path(feed.author)
        else

Why not… While weird, to render the view for this model, one has to go to another site. This is the new age.

 
          redirect_to feed.author.remote_url
        end
      end

      format.atom do

We do have to provide a rendered feed to the hub, and this controller does it. Publishers will also view a feed in order to verify their subscription.
