iPad and Social Reading

I just finished reading this article in the School Library Journal. The author points out his disappointment that Apple did not query librarians regarding the functionality of the ereader software for the iPad. He is left slightly wanting and BORED. I went to Best Buy recently on a whim to check it out. I have to agree with him. Yes, it is pretty. Oooooohhh, Aaaaaaahhh. Ok we got that out of our system. But in regards to reading an ebook on the iPad, there's not much more to it. The author of this article makes the case that Apple could have allowed the reader to not only highlight selected passages, but to be able to post them, comment and collaborate with others. This would basically turn the ereading experience into a social media/collaboration phenomenon. My husband says that its coming. The author even apologizes ahead of time if its on its way and just hasn't been unveiled yet. I have to agree, that sounds way cool. Now, when can I get one?
