 Either since updating to WP 2.0 or 2.0.1, I have noticed a problem with my
 RSS comments feed:

 http://www.red-sweater.com/blog/?feed=comments-rss2

 My news aggregator (NetNewsWire) has failed to notice changes to this
 feed's contents, even though the raw contents are verifably different if I
 load them from the command line with curl.

 I traced the problem to a stale "Last-Modifed:" header in the HTTP
 response to the above URL.  No matter how much time passes or how many
 comments are posted, the date stays the same. It seems that modifying any
 *post* (not comment) will cause the Last-Modified header for the feed to
 be updated.  So whenever I update my blog, a slew of comments come through
 the separate comments feed. This is a less than ideal behavior for my
 readers, especially when there are lulls in my regular posting, but
 comment activity is continuing at a reasonable clip.

 It seems that the Last-Modified data included in the comments HTTP
 response should correspond to the date of the last comment posted, not to
 the last entry posted.
