Comparisons of social networking tools for readers

If you're goin' all 2.0 these days and debating about which one of those online book cataloguing tools to use (I use LibraryThing, but don't let that sway you!), here are a few good comparison articles:

• Bookseller Chick: GoodReads, Shelfari and LibraryThing: A Features Comparison


• Ramblings on Romance Etcetera, Etcetera: Book Cataloguing - An analysis of online sites


• Online poll about social networking tools for readers - LibraryThing was winning, but just barely, when I voted...

The Dear Author blog mentioned one tool I was not even aware of (gasp!): Readerville. Warning: today's featured book has a very scary cover image. Rather a little too Hannibal Lecter.
