technorati and librarything

I had a quick look at technorati, and the interface with the ads was so irritating I nearly switched off, did some searches, very cool. Librarything is great of course, and as I said before mos was innovative in setting up our book clubs there, I did a comparison with shelfari and it seemed to be in it's infancy, not much there, another thing about these sites is that I often disagree with the reviews, a bit like our very own great reads!
