Browsers with feed-reading capabilities like IE7 and Firefox indicate the presence of an RSS feed on a site by having an icon flash in the toolbar:
They’re not triggered by an actual link (
a href = “…”) in the page, but by some html in the head of the page, and was proposed some 4 years ago to make subscribing to rss feeds more user-friendly:
<link rel="alternate" type="application/rss+xml" title=”RSS” href=”http://pascal.vanhecke.info/feed/”>
A feed reader just needs a regular page url (like http://pascal.vanhecke.info/), and will figure out for you where the corresponding RSS feed is (at http://pascal.vanhecke.info/feed/ in this example).
IE7 and Firefox hide this “complexity” for the user, but sometimes you simply need this actual feed url, to use in code, or to have a look at the RSS source itself. Then this RSS discovery bookmarklet by Martin Dittus comes in very handy: just a click displays the available feeds – see my install instructions for a Google Bookmarklet if you’re not yet familiar with bookmarklets.
