For me a manager can be a benchmark whether the bounty will be successful or not. It is worth noting that today there are almost a lot of bounty managers, but that gives us a certainty only a few people. I think one of the best reputable managers is yahoo, sylon, and deadly he is a trustworthy persons and he connects the project owner with all of us who try to follow the bounty provided. Yahoo, sylon, and deadly is a wonderful manager and everyone believes in it. He has been building trust for several years and I think he has brought out everything he has.
