Del.icio.us and Technorati

I've used del.icio.us before and can't honestly say I can envision ever using it. If you know how to use google, then you'd struggle to justify the amount of time required to set del.icio.us up properly. Technorati is new to me though and looks like somthing I'd quite likely use. The ability to search blogs is becoming a much more important tool these days as blogs are becoming quite commonplace so I see Technorati as filling a niche in information searching.
