A friend who was at SES in NY passed along to me some info about a company he talked to for a bit. They are http://www.clickbroker.com and overall it looks somewhat similar to Textbroker. Pricewise they are roughly the same depending on the quality you want. Textbroker is cheaper for 4 stars and less but if you want 5 star articles clickworker is cheaper. It will be interesting to compare the quality of the two and see how these articles rate.
And supposedly through this link http://www.clickworker.com/SES2011/ you can get a $52 credit although I signed up, placed an order and didn't see that credit. Maybe it will show up.
Anyway, I ordered 14 short articles (100-150 words) today and when they come back I will let you know how they are and how quick the turnaround was.
Very quick turnaround on this. The project was finished the next day so that is good. But overall the quality isn't great. I could get this level of work from a cheap outsourcer.
I did get the $52 credit so after that is used up I probably won't get another project through them.
Thanks for the feedback, I'm looking around too. Currently testing a native English at home mom type.
