Starting 2015, I began funding contract work by Alex K. Chen and Issa Rice, mostly related to content creation. You can see some of the early history at my sponsored Wikipedia editing page. I ramped up the volume of contract work and the amount I paid for it in 2016, and maintained a comparably high level in 2017. You can see full details on the contract work portal or in the GitHub repository. As of January 2018, I have funded about $75,000 of contract work, and the main active workers are Issa Rice and Sebastian Sanchez.
