Interesting Uses for RSS Feeds

How have you seen feeds used?

Most feeds are used for news and blogs, but there are quite a few feeds with entirely different purposes... What are some that you have seen?

I'll start with...
One of the things I've noticed lately, although not the most interesting, are job feeds. The popularity of these seem to be rising. Employment listing sites are using feeds to display new openings. People looking for jobs can now just subscribe to a bunch of feeds and quickly run through all the new job postings.

Here's an interesting one: RSS feed of FSOB (For Sale By Owner) properties. I'd like to see the local market pick up RSS more - maybe my local watering hole with drink and dinner specials.

Here's another one...

There's a feed that allows you to read the bible a chapter a day. What's interesting is that you can change the date in the feed's url to today's date and the feed will start with genesis 1.1. As long as you keep the same date in the url, each day you get the next chapter. (&startdate=2006-02-13)

This is incredibly interesting to me, because of the possiblilities... You could replace the bible with any book, or even a tutorial. I could start a new book today, by placing today's date in the url, and each day get a new chapter. Or 2 new chapters - there could be a param in the url specifying how many chapters a day you want (&startdate=2006-02-13&chapters=2). Or I could start a new tutorial today and get a new lesson everyday. Miss a lesson? I would just change the date in the url to get me back to where I was.

Banned rogue bot feeds. User agents or IPs that trigger bot traps have their header info and IP distributed to participating sites who use that information to dynamically update their .htaccess files.

Our of the hottest RSS applications are Newsradars - constantly updated thematic channel of highly relevant web references that are gathered in accordance with single or multiple specific, persistent search criteria. Radars can focus on anything: topics, people, opinions, products, news items, events or passions. The constant updating of the channel is accomplished by leveraging the RSS technology to its full power.

Our site <snip> features several RSS Newsradars.

We have two radars: JobExposer and Accounting JobExposer aggregating the Canadian IT and Accounting job feeds
<snip>

The site features radars related to RSS Enterprise Tools and Newsmastering
<snip>

We also have four Radars monitoring subjects important for every career-conscious IT professional: Resume Mastering, Interview Preparation and Soft Skills for Techies <snip>
