It's hard to talk about what you are reading when it's on a Kindle. It's always, "How do you like the Kindle?"
Never, "Oh, Nora Roberts! One of my favorites. Have you read any of her other books?"
This also has benefits. I'm not embarrassed when I'm reading the book after the movie came out and there is a picture of Will Smith on the cover or something with a naked lady on the it like Lady Chatterley's Lover
What the Kindle needs is a way for me to share digitally with other Kindle owners what I'm reading and what I think about it. They need to make it more social. I've used Shelfari for a few years to display my bookshelf digitally and to discover new authors through other readers with similar interests. Recently, Amazon bought the website so I'm hoping they are planning on tackling this issue. I'd like for the books I buy through the Kindle to show up on my Shelfari shelf along with my progress as I read them. If I post a comment or bookmark a page on the Kindle, I'd like for it to transfer digitally to my page. Then I should be able to subscribe to my 'friends' shelf and have it synced with my mine. If I'm reading a book a friend has, it will tell me and alert me if one of them has commented on or bookmarked the page I'm on.
Currently, I can subscribe to RSS feeds and have them emailed to my @Kindle email address daily on my device. I should be able to subscribe to a Shelfari feed and have it compared to my feed and have those results synced with my device at the appropriate time.
The thing missing from my digital reading experience is the conversation that surrounds a book when you're reading it in public. "Oh, I just love Nora Roberts!"
