Amazon using Kindle owners' highlighting

MSNBC's Red Tape Chronicles reports that some Amazon Kindle (ebook reader) users are concerned about a new feature whereby Amazon will now remotely upload and store user notes and highlights from Kindle, which it then compiles into "popular highlights". Just as readers can use highlighters or make notes in the margins of print books, ebook readers offer users the ability to highlight text and make notes about what they are reading. Kindle users who highlight passages will now have a record of those highlights sent back to Amazon servers - and many users don't realize that this is happening. An Amazon spokesman denied that the new service raises any privacy issues with consumers, comparing it to the popular "Customers Who Bought This Item Also Bought..." feature on Amazon.com.
