The actual problem is, I do not even think bounties are useful for project. There are thousands of projects on social media shared by those people. So how can one be seen better than other? Bounties should turn to 'Social mining' so people should compete with each other to create useful content. I really like the social mining concept to be honest.
The concept of bounties and social mining almost the same, to promote the project and expand their reach. Bounty hunters are creating useful contents as well, competing with their competitors to receive a higher stakes. I'm not against this social mining, I like the idea but they should add more campaigns on the table like signature campaign.
