Technorati

When performing a keyword search on Technorati for "Web 2.0" I found the following:
Blogs: 14
Posts: 75
Blog Directory: 0
Tags: @ 20 of the latest articles that were tagged

With a keyword search for "Library 2.0" I found:
Blogs: 0

Looks like web 2.0 is the front-runner!

When trying to explore Technorati's popular blog, searches and tags, I found this message: "Technorati's Popular section is currently unavailable. Popular features will return in the near future. Popular videos are available now in the new Technorati Video Section. Read more: http://technorati.com/pop#ixzz1RiduLQEY"
The popular videos are fun to watch if you have some free time.

I tried following the link to learn how to tag posts with HTML (http://www.technorati.com/help/tags.html), but it doesn't seem to be working...anyone else have this problem?
