Technorati worthless?

There has been a lot of noise in recent weeks over the performance of Technorati compared to other similar tools.

The Blog Herald is now reporting that Jason Calacanis feels Technorati is worthless! Personally I think that is a big call but I do agree that the service is really lacking.

I have moved most of my searching to Feedster and Pubsub as I receive errors more often than not when using Technorati. this is a pity cause I really like the new interface that combines a whole heap of tagged content into one screen.
