RSS feeds are pretty darn useful for a lot of things. And WordPress makes them really, really easy. If you want to insert an rss feed somewhere then according to the type of feed you need, you can just use a pretty repeatable pattern to do so. Basically, following the site you would use /wp-rss.php for rss, /wp-rss2.php for rss2 or /wp-atom.php for Atom feeds. For example, to get a feed of this site in rss you could use the following:
https://krypted.com//wp-rss.php
Or rss2:
https://krypted.com//wp-rss2.php
Or rdf:
https://krypted.com//wp-rdf.php
Or Atom:
https://krypted.com//wp-atom.php
