Apologies to Feed readers

I've been sorting through and reorganizing some old posts and galleries on the site, and for some reason this is not playing nice with the RSS feeds.  I'm editing some old posts, updating links or categories, and although this shouldn't trigger a 'new' item in the RSS feed, some entries are doing this (and others aren't, which is why I am annoyed - difficult troubleshooting).  I've only seen two entries go into the feed, while I've actually edited close to ten, so I'm just going to accept this as a bug and not deal with it - I hope it doesn't cause too much trouble to the feed readers.
