Has there been a blog or form post explaining why Beeminder is considering a new pledge schedule? After a quick search of the blog/forum, I didn’t see one anywhere.
One reason I ask is that the Beeminder FAQ has a convincing argument against pledge schedules like the new one:
Q: Why not just double the amount pledged each time?
The idea is that you want to very quickly reach an amount that motivates you to take your yellow brick road seriously. At first we thought we’d just double the amount each time but then realized that that means that by the time you’ve found your Motivation Point, you’ve actually wasted approximately that same amount in previously paid fees. That sucks since by definition the Motivation Point is a scary amount that you definitely don’t want to lose. Yet by the time that amount is motivating you, you’ve accumulated that much in losses! So we wanted it to increase more steeply. With the above schedule you’ll never waste more than half of the amount that eventually motivates you to stay on track.
I’ve always really appreciated this answer and taken it as strong evidence of Beeminder’s good faith—Beeminder would make more money from derailments with a flatter pledge schedule, but chose to treat customers better by adopting a pledge schedule that gets people to their Motivation Point at lower cost.
Now, however, Beeminder is (seems to be?) moving to a flatter schedule that sounds a lot like the one rejected in that FAQ answer. I’m sure there’s good logic behind this (I trust the team!) but I’d really like to know what it is/how Beeminder’s perspective has evolved since that FAQ entry was written.
