From the Wired online archives, dated 7/30/2001:
MIT’s Media Lab is experimenting with a tool for indexing the most popular hypertext links across thousands of weblogs and has ambitious plans to turn it into a resource for the mass media.
Launched last week, Blogdex is like a search-engine spider that visits about 9,000 weblogs a day looking for hypertext links.
Things have changed a bit since then.
