Yes I do also agree that Yahoo is one of the best campaign manager out there. I participated some of his signature campaign in the past and what I say is he manage well and the payment is on time.
We can see it in the pool obviously that yahoo62278 is the best base on the people or bitcoin users and maybe we can award him the People Choice Award in Managing Bounties if possible. I am also a worker of yahoo on his past campaigns where I participated, Hhampuz joined many campaigns and also julerz12 where in I participated on his past campaign and now with his new one. Many bounty managers are here around but not all of them are listed so better to share this thread to you local boards or even in community groups.
