A web feed (news feed, RSS feed, syndicated feed) allows users to subscribe to frequently updated content. All blogs, all news sites and most personal websites have feeds readers can subscribe to.  It takes the need to frequently check the site away.  You get notified when there’s new content.

Why does milton.ca not have feeds for every subsection (it does for the main page.  Even if you are in a sub-section, you only get RSS for the main page)?  I want to see the list of all registered candidates for the 2010 municipal election. I do not want to have to check the document every day. Instead, I want to be able to subscribe to the feed, so I get notified in my RSS reader (I use Internet Explorer for it) whenever they change that page. 

[Shameless plug: you can subscribe to my RSS feeds by either clicking the feed icon in your browser or by clicking this link, if you use an external application.]
