This is a rather strange and unlikely to be successful question, but I’ll ask anyway: do you, or anyone you know, have autodiscovery link elements for an equal number of different types of feeds, where the contents are actually different?

If you see

<link rel="alternate" type="application/rss+xml" href="/index.xml">
<link rel="alternate" type="application/rdf+xml" href="/index.rdf">
<link rel="alternate" type="application/rss+xml" href="/comments.xml">
<link rel="alternate" type="application/rdf+xml" href="/comments.rdf">

you might guess that an equal number of each type meant it was the same content in different formats, but is something like

<link rel="alternate" type="application/rss+xml" href="/index.xml">
<link rel="alternate" type="application/rdf+xml" href="http://del.icio.us/rss/user">
<link rel="alternate" type="application/atom+xml" href="http://user.blogspot.com/atom.xml">

too common to make that a safe guess? (And the bonus question, how many browsers failing to show more than the first feed would it take to make people change, by faking the type I guess?)

Extra credit for real-world example URLs, and for speed. Thanks.
