So I offered $1 per post to write 50-100 words summaries of the news. Depending on the content a writer could add four to eight posts an hour, getting faster at it as they improved their skills. We had about 50 writers on the program, but could easily have had many more. We were overwhelmed with people wanting to join the program and had over 1000 people on our waiting list.
At first, But the $1-per-post program attracted a whole different community: mainly women, many of them minorities, who like to work-at-home. We actually saw this as a big plus because they were no-nonsense about doing the work, and gave diversity to the content, something Wikipedia struggles with. We paid out in Paypal and some people would literally do some work so they could get some food for that day.
I think too many companies think of crowdsourcing as a way to get cheap work, but it's really good to get diverse workers.
After paying out $20,000 for 20,000 posts we changed to a revenue-share system, where writers earn more as the site grows. That presents a different challenge: finding writers who will put in work now, with the hope of a bigger payout later.
