Making feeds automatically discoverable

I am a big fan of reading websites via a feed reader. Not all websites offer one, and not all that do link it prominently. A good thing therefore is, that a standardized way to make feeds discoverable for feed readers exists. So, when I find a website that I'd like to subscribe to, I can simply try to copy the url into the reader of my choice and chances are the reader is able to automatically dig out the URL of the feed.

All that is needed to make it work is a single link tag added to the head. It has three mandatory attributes: href of course for the URL of the feed, rel with value "alternate" and type with a value of either "application/rss+xml", or application/atom+xml, depending on the feed format. The title attribute is optional, but it's useful if a site offers multiple feeds.

In quite a lot of cases it works like a charm. It used to work here as well. Now, guess which self-proclaimed fan of feeds thought it would be a good idea to rewrite the template of his personal website and managed to forget putting in the following line into the head:

<link href="" rel="alternate" type="application/rss+xml">
