OUTDATED: What do I need to subscribe to a feed?

The standard method of syndication is using the XML-based RSS format. RSS stands for Really Simple Syndication, RDF Site Summary, or Rich Site Summary, depending on whom you talk to. To syndicate a site's content, obtain the full URL of the RSS page providing syndication. Common file tags for RSS pages are .rss, .xml and .rdf. Example: http://slashdot.org/slashdot.rdf.

Most weblog sites that offer syndication will have an obvious link on the main page. Often you need only look for a red XML button, such as the one Drupal uses for site syndication.

Some sites do not make their RSS feeds as easy to find. Or maybe you want to find a number of feeds on a given topic, without extensively searching the web. In that case, try an RSS syndication directory such as Syndic8.

NOTE: Enable your site's XML syndication button by turning on the Syndicate block in administer » blocks.
