The best thing about this site is that once you choose something to read, whether it's an article or a book, the site will suggest other related books, articles or snippets that might be of interest.
The site will contain free content as well as 99-cent downloadable "reads," similar to the current iTunes model.
Site to see: JoongelThis uber search site contains "direct search results from the 10 most viewed Web sites in a specific subject or subcategory. The Joongel application can be used in different platforms, such as search plugins, expert Web sites and the Joongel main Web site." What I like about this site is that you can see at a glance all the logos of the various Web sites that you are searching through and you can search for images, videos, print, shopping, etc.
