good reads vs librarything

I recently learned about goodreads.com, which compared to library thing is more slick, more social, and has neat features like author's lists, and the ability to sort into different types of "shelves",such as a "to buy", "to read", "to leave on a bench for bookcrossing"...

One problem on library thing is the lack of discrimination between books I have and books I wish to have... However, the geek in me likes librarythings taggability (is this a word?), and it's data-driven method- one can create "clouds", which suggest new avenues to go on from previously read books, as well as generate statistics such as "median/mean library obscurity", as well as generate a gallery of pictures of the authors in your library

While migrating my library to GoodReads, I stumbled on a prescient link from my 2005 blog to the NY Times best 100 books of 2005, which I had come across in December 2005 while doing a winter elective at the Mayo Clinic, elicited most likely by my friend Kat in Minnesota. As I looked over the titles picked as excellent in 2005 by the NY Times, I noticed one, Cormac McCarthy's, has since been made into an Oscar Winning movie- "No country for old men", (a nice addition to the 2007 Pulitzer Prize for "The Road" from this secretive author, and another is Friedman's "The World is Flat", "Glass Castle", "Freakonomics", Marquez's "Memories of My Melancholy Whores" were all in there.

In retrospect, I should have picked up Ian McEwan's "Saturday", a book about a day off in the life of a neurosurgeon...

Fast forward to this year's list, 2007 , and I noticed these ones which look good- "Matrimony" by Joshua Henkin, "Septembers of Shiraz" by Dalia Sofer, "Then we came to the end" by Joshua Ferris, and "How Doctors Think" by Jerome Groopman...

My only question now is where Oprah gets her list?
