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. It extracts the links and ranks them by popularity. The top 10 are published daily on the Blogdex site.
