Another item to get on the record here..

Yahoo and DMOZ, while tremendously useful (they build flow almost as well as
search engines) have been built around centralized editorial systems.

We've conceived a directory system that is not centralized and can grow as
the Web itself grew. There is no single home page to the Web, why should
there be a centralized home for the directory structures of the Web?

What's been missing so far are tools and an "inclusion" architecture.

We now have both, working well.
