I love LibraryThing. I am in the process of adding all of my books to it - much more fun than a simple database. A particularly satisfying element of this is finding not just a catalogue entry for my particular edition of a book, but selecting a cover that matches. As requested, I will attempt to add the LT link to my blog.
Tried the Technorati exercise. No joy with the slnsw2008 search - perhaps now too old? Did the same search in Google, and found Flickr, blogs - the works. Makes me wonder how relevant Technorati will remain... :-)
