The most extreme example that comes to my mind was Google Image Labeler. I said "Was" as I've just noticed that "Google Image Labeler is being phased out, and will no longer be available as of September 16, 2011.". Google Image Labeler (http://images.google.com/imagelabeler/) was a total farce or simply brilliant depending on how you look at it. Behind the disguise of a game, contributors were asked to label random images in order to improve the relevance of Google Image Search. Some have spent several hundreds or thousands of hours for free; the top contributors reaching around 3 million points. The only benefitor in term of money is Google.
Your time is not free but what can I offer in exchange of you contributing to my website? Some examples in no particular order:
- Nothing, just a good reliable product/service. In a way, most people are happy to use services such as Google or Facebook for free. The service providers get money through ads and the user get a good service.
- Freebees: every week, the top 100 contributors automatically enters to a draw to win an iPad.
- Some of the profit: cut of the profit generated by the content you provided. Many blogs or user content generated websites do reward the author based on the success of their content.
- No Ad: Similar to paid applications that simply removes the ads, contributors could have the option to opt out of ads.
- Extra features: Contributors get the advanced features that would normally be given to paying customers.
- Reward: each contribution gives the user points and points can be exchanged against money/product/whatever.
- Badge/Karma: that's how ycombinator/stackoverflow works.
- Amazing deal: Through partnerships you get x% discount on products/services.
Do you think contributors of a community website should be rewarded? If yes, to which degree? What would you like to get offered?
