You can make money working for Amazon.com, doing things that computers can't, by working on HITS.  A HIT is a human intelligence task. You have to join Amazon.com, & then join as a TURK, then search for HITS that need completing. You can complete as many HITS as you want to, can work from your home, & earn money that can go toward the purchase of books or other products at Amazon.com or get the cash once you've earned at least $10. You won't become independently wealthy doing this, but every little bit helps!
