So, I've been on vacation for a week or two and am a little behind....so I'll get right to it.
LibraryThing....reminded me of Shelfari but with a lot more features. I added a few books to my collection, tagged and rated them, then read some of the reviews by others (which was interesting). I think I like the look of Shelfari better than LibraryThing, but I could see how it would be beneficial for me to keep up with my personal reading collection using this site. Honestly, right now I am following so many blogs and newsfeeds that I don't have the time to keep up with what everyone's saying....BUT I went ahead and found a few more groups to follow ;)
