Related to his original idea: I think it's simply fantastic. Not only does it help avoid writers block (You constantly have a stream of stories to create), but it's forced practice. Nobody says Mozart's first few works were brilliant. It wasn't until he practiced for years that he became a virtuoso. An approach like this, while easy to view from the lens of simply making people happy, is an investment in one's creativity and writing skill that will pay off in leaps and bounds years down the line.
It's just so unfortunate that the internet makes it so hard. You're either loved, hated, or ignored. He, thanks to an unlucky picture angle and loss of context, fell into the 'hated' category by many. I applaud the effort to just do it. It is funny how many view the real world as hard and the internet as an easy escape, yet in his experience, it was just the opposite.
