Beyond e-commerce and its trappings, some of the more recent Amazon endeavors have the company branching out into new realms. Amazon's Mechanical Turk project seeks to combine community, technology and compensation. Using the Mechanical Turk system, software and Web developers can post tasks they need help with, usually tasks related to things computers can't do but humans can, like quickly caption a set of photos. Anyone can post a task, and the person who completes it gets a small amount of money in return. Amazon gets a commission on each completed transaction. In a much more visible trek into the unknown, Amazon has funded the A9 search engine. It has full search capabilities, mapping functions, a toolbar with pop-up blocking and an easily accessible personal search history. A9 also provides a "Diary" where you can makes notes to yourself about specific Web pages and lists of recommended links for you to check out based on your previous searches. In keeping with Amazon's omnipresent marketing techniques, you can sign up to get an Amazon.com discount for using A9 on a regular basis, and when you type in a search term, you'll see a display of Amazon book results related to that term.
