I changed the path organization of my CMS, thus changing the permalinks in the RSS feed. Gasp! Sorry. I wanted to use a naming format that presents the entries like they are a collection of real files and directories, rather than making it obvious that it is one script that is retrieving an entry from the database. In other words, now rather than getting to an entry like this:
http://binrock.net/view_entry.php?eID=254
It is accessible like this:
http://binrock.net/cms/entries/254/
Likewise, the URL for a month's worth of entries in the archive changes from this:
http://binrock.net/view_archive.php?m=5&y=2004
to this:
http://binrock.net/cms/archive/2004/5/
It's more logical and intuitive. Also, now Google will actually index the entries, something it apparently doesn't do when you use a querystring as my site did before. I may be be making the same change to the photo gallery sometime soon.
The old links still work (they forward you to the new URL for whatever you were trying to get to), but since the URL of an entry is used as its unique identifier in RSS, if you are subscribed to the RSS feed then your feed reader probably just thought there were 15 new entries, and you were given the unique honor of being able to reread my recent wit and wisdom. You're welcome for that. And don't worry, it shouldn't change again anytime soon unless I find there's some downside to this new system.
