Old Yahoo! is gone

The bad news is that the copy of the Yahoo! directory hosted at this subdomain has gone as a result of a deliberate clean-up.

The good news is that the link directory ZOMDir is in theory a much better alternative (at least the number of broken links is much much lower).

Lesson learned

Research based on this old Yahoo! directory learned that the half-life of a link is two year.

The Maintenance Frequency at a Glance tool predicts the number of broken links on your website based on the frequency with which you fix broken links.

That's all there is to say about this.
