Talking with Tianning about blogging – I bet a blogging platform (or just a plug-in) that would allow people to pay others to review and correct their posts for English could go a long way. It would work something like:
Author: I like eat food.
Author: (please edit – will pay X for corrections. Could be per-mistake model)
Editor: edits to “I like to eat food”
Author: reviews correction, accepts, money transferred to editor
This would allow for an excellent barter system since people with different languages could correct each other. It would also be a good system to throw onto the Amazon Turk.
