A quick look at the list of services offered shows that many of these are services academics frequently outsource:
...data entry and digitization, web development, image and site moderation, application testing, video and audio services, project management, research assistance, virtual assistance...All workers are trained and you can have transcription work, for example, delivered within 24 hours, for a very reasonable price. It's great for those who need the job done, and for those who want to do it. I plan to send some interviews to be transcribed very soon, and I write a post to let you know how it goes.
Here is a video of the founder of Samasource. Laila, speaking at TED. Take a look, give them some work, help make a difference :)
