In spite of the fact that I wrote the feeds.php recipe, I'm
really a bit of a newbie in this area, too.  But if the problem 
you're experiencing is appearing in Firefox, we really ought to see
about fixing it.

I think that some of the Firefox extensions associate "read/not read"
with individual urls, so once a particular url is marked as "read",
it doesn't show up again, even if the contents of the url change
(and the date along with it).

I know that one thing many people have tried is to include a date
of some sort along with the url, so that the RSS reader gets a new
url every time the article changes.  This can be done in config.php

    $FeedFmt['rss']['item']['link'] = '{$PageUrl}&when={$ItemISOTime}';

This causes a "&when=" parameter to be added to each of the
items' urls, so that whenever the page changes, it gets a new
feed url.

Personally I'm not a big fan of that solution, because it implies
that the page with different dates appended might appear differently
in the results.  I think that instead of simply marking a url as
"read", an RSS reader ought to keep track of when the url was read,
and not display the url as long as its date doesn't change.

I'm not sure about this one -- are you talking about the watch lists
using the Notify capability, or some other watch lists?
