 same URL will give you the same result every time.

 Basing it from the URL really wouldn't be that much of a difference than
 just using the URL itself, especially since there wouldn't be a different
 GUID for revisions. For example if there is a post made and it is read by
 various feed readers with one GUID, by changing the revision it would
 affect the GUID noting that the last read from the feed reader has been
 changed, and nolonger valid. This is especially sensitive for posts that
 have time sensitive information such as Paypal buttons on items to be
 purchased with a limited quantity. I've been working on a feed reader and
 because of the problem of posts being able to be updated, I need to verify
 that the title and contents have not changed. If they have been then I
 update the post.
