From the report:
Looking first at the number of projects, it is obvious that this subcategory of projects is bonkers:
There is a strong and steady growth of the number of projects that are funded.
There was no “potato salad” speculation effect in the second half of 2014 (at least, not as visibly as in other parts of the Kickstarter platform).
The number of projects failing is stable, meaning the success ratio is steadily increasing (62% of the projects got funded in the first half of 2017)
