Technorati
Lately, I've been looking a bit more into Technorati and it's system. Quite impressive, and very interesting. I already added a technorati link to my dutch weblog but hadn't done that here yet. So just now I've added the Technorati link here as well.
Now, I'm already planning to write a plugin for Nucleus to include Technorati Tags in that system, but I guess it would be good to also have an extension for Pivot. I don't think the extension system is not really documented yet.
