I don't know about the rest of you but I can't believe it's only been two weeks since we moved over to GitHub! Hopefully people are still viewing it in a positive light. :)
One complaint I have heard consistently is the required review sign-off on PRs. To do some A/B testing of this, I have switched that requirement off but switched on the requirement that Travis tests be passing.
In two weeks I will be starting a conversation about the new workflow to find out what people think we need to tweak, add/create, or remove in the process. At that point we can make a final call if this situation is better than requiring reviews, or if we want both CI and reviews for each PR.
