Other people talking about metalinker: one, two, three, four, five, six. It’s weirdly popular in Germany too.
One of the best comments (and most useful potential features) comes from Webvoice: “This script automates the “other linkers” links I manually add from time to time. However, Blogdex should be an API to make this application more compelling. The metalink wouldn’t appear if you’re the only one to have posted any given link (I hate links to emptiness,) and the number of other referrals to that link (e.g. [3]) would be more useful than just a link to the list of other links (ain’t it getting too meta to make sense?)”
