Ok, I had a goodreads account for a while but there was nothing in it. I just put all the books I had in my paperbackswap lists in there so now it has the books read in the past 2 and a half years and the up to date TBR. Vox lets me put a goodreads widget on my sidebar but LJ does not. Oh well.
Cut down my TBR by ten in the past couple of days – I just took out some books I didn't think I was ever going to read.

I love Goodreads, it's my latest addiction!
Ooo, ok, I found it through your blog and have added you. We have a good number of books in common! I bet we'd have more if I add the rest of my bookshelves to it!
I managed to add all my books to GR when I moved to my new apartment, I had to sort them all out anyway! One of the best features of the site for me is its interactivity, I love chatting about books with my friends and see what they're reading or recently bought.
