I can only imagine that this is wanted by users who let their feed reader
display the feed item as "complete" HTML page (the site the feed links to)
instead of the feed itself. I cannot really figure out why such users
would complain about a characteristic that they have (hopefully?) enabled
by themselves. Or maybe some weird web-based feed reader dismisses the
feed item altogether and only shows the linked items, which is the only
case I can think of that might trigger the request for the /rss page.
Anyways, here's a version that should satisfy both regular users and
whatever weirdos who came up with this braindead idea: In the feed item,
you add a link "Complete article" as part of the regular feed item text,
and everything else (including the real "link" property that points to the
/rss page) stays the same as it is now. The /rss page also stays the same,
and does not get the added link from the feed item.
That way, I've got (a) the teaser / editorial comment in the feed item,
(b) a link to the actual content and comments in the feed item too, and
(c) nothing changes for the folks who view the linked HTML instead of the
