Amazon's Interesting People feature lets you bookmark authors or reviewers you're interested in, and enables you to see their latest Amazon activity on your Profile page--new book reviews, tagging activity, etc. To add someone to your interesting people list, go to their profile page and, in the box labeled #Your Actions#, click the link Add to Interesting People. You can search for people to add to your list by selecting #People# from the search pull-down menu at the top left corner of your profile page.
