I actually think the openness is very important as well. Many companies(/C levels/managers/employees/clients/etc) are still stuck in the "heads must roll" mindset, where a mistake is punished rather than used as a learning experience for the employee and for the company.

I think at the very least it'll turn the heads of a few employees that are living in fear of being fired for a typo by showing them there are still decent employers left in the field.
