I promise that if I ever decide to change the url of my RSS feed that I will do one of two things:
1. Post a message on the old feed that points to the new feed; or
2. (preferred) Redirect the old feed to the new one so that you do not need to update your news aggregator. I'll even use a 301 redirect so that your smart aggregator will permanently change the URL.
It's something that doesn't seem so hard to do, yet saves a bunch of people (ok, 4 in my case) the aggrivation of having to figure out why their rss aggregator isn't picking up new entries or (even better) the inconvience of having to update their aggregator to the new feed url.
I understand that sometimes you want to change software or the layout of the site, but seriously, can't you do this for your readers?
