If you're going to create a bounty, you need to tell people what you're giving it for. Steem bounty might help you get decent quality comments (certainly nothing worthy of real praise) on your blog, which give you an ego boost, help you to delude yourself into believing that people actually like your awful grammar and missppelt posts and think that people might be interested in what you have to say. Unfortunately steem bounty doesn't guarantee that you'll get good comments on your post. You have to tell people what they'll get the bounty for, and honestly give them the bounty based on your assessment criteria.
