Amazon has purchased Shelfari, the smallish social network built around books. The two companies have always had a financial relationship -- Amazon after all was an early Shelfari investor.
The book-centered social media business has been growing at a healthy clip, and this acquisition seems to signal that Amazon has no desire whatsoever to be anywhere but at the center of any relationship anyone has with books.
ReadWriteWeb noted the innovative UI in this post, which is a clear advantage over the larger but rather spartan LibraryThing. Now, don't get me wrong, I am a LibraryThing user, have been for well over a year, and I am satisfied with it in its current form. That being said, I will be the first to note that LibraryThing's appearance is a bit...unzippy. Given the size advantage LT has over Shelfari, however, it is apparent that LibraryThing's more featured experience is preferred by many bookies.
Thanks for reading, and don't forget to write.
