I really commend YC for supporting this. If my startup ever succeeds, I definitely have a duty to give back to the world which has given me incredibly luck (and benefits). I just took the pledge and realized it would be nice to have a sliding scale based on exit size. If I have a relatively small exit (<$10M), I would prefer to donate substantially less (maybe 10%) but for a larger exit I would scale up closer to 50%. Obviously I can still donate more if I want to, but it would be nice to pre-commit. Also, it would be nice to include an option for employees.
