While cleaning out my email (only 50 unread messages!), I stumbled across a neat service called FeedTier. The site lets you generate an RSS feed from any page - no orange icon required! From the FeedTier site:
FeedTier is a web feeds generator for web pages without an existing syndication format. FeedTier performs content analysis, picks-up the most prominent cluster of hyperlinks and automatically generates RSS web feeds from web pages without existing syndication. FeedTier (beta) is an experimental service and free for personal use.
