At this juncture, I would like to repeat my recommendation that Foundation employees to immediately join the Union for Non-Profit Workers, IFPTE Local 70:
Furthermore, the discussion concerning innovative ways to fund the best long term editors through, for example, a new spin-off foundation other than the WikiEd Foundation or something like http://arowf.org/ was supposed to be, gives me hope that there is an easier solution than paying the best editors merely for accuracy review. However, I don't think the donation pool would do a better job. Having said that, I want to encourage additional brainstorming along those lines.
What if there was a spin-off Foundation with a mission to identify and pay bonuses to the best long term editors?
