Everybody's too busy bitching and moaning.
You can get browsers to auto detect the feed by adding the following line for each feed URL in your META tags...
<link rel="alternate" type="application/rss+xml" title="RSS Feed Title" href="http://yourdomain.com/backend.php" />
RSS-Fit works really well at giving RSS to modules that may not necessarily have RSS. If you combine that with
Feedburner.com, you can really enhance your feeds.
There may be a way to automatically detect whether a module has a feed or not, or a way to build a feed directly off of the smarty output or DB, but that's beyond my skill level.
Don't know if that is what you were looking for, but at least I gave it a shot.
