@btcYoshimitsu: that sounds very interesting, can you send me examples of their bounty programs? the challenge here is evaluating the quality of the writing and the number of readers you have. would like to hear your perspective on this! thank you for your comments.
For number of readers you can use services such as alexa and do not forget to take a look at bounce rate values. Also if you have worldwide team, you could make a campaign limited to your team (mother) language at first, this way you will have more quality control over those articles

@falala69: yes I like your approach. I would say, if there are any fans of our project here who have a blog or write for a good website that has good number of readers (we'll verify using similarweb.com and alexa), then please PM me with the name of the website you write for and your proposal. Thank you for your advice!
