The 141 was different. It was fun too. I was a part of it and delivered what was paid for. The amount of pledges were predetermined, paid upfront, and most of them were for some privilege or the other regarding the story. In this case, people who would take the pledge, would have to pay when the determined time is up and the amount would be based on how much a writer has written. Not about naming a place, or a character, the opportunity to see the story before it's posted for everyone to see, etc.
In the end, the decision is yours, of course. I thought this would be a good way to bring a bit of income to your budget.
