If you charge towards the charity then a user doesn't feel committed when he/she slips.

If you believe the point is to "make people feel bad if they fail" then you really deserve nothing from this. It conflicts with the stated purpose entirely. The goal should be to entice people to succeed, not punish them if they don't.

Edit: For reference, the original comment I responded to stated "If you charge towards the charity then a user doesn't feel bad when he/she fails."

To solve this, Stickk (a similar service) has "anti-charities."

StickK's list of 23 anti-charities (their anti-ness, of course, being in the eye of each goal-setting beholder) includes: The George W. Bush Presidential Library, the William Jefferson Clinton Presidential Library, the NRA, the Educational Fund to Stop Gun Violence, and various fan clubs of opposing sports teams.

Here's our (Beeminder's) argument against anti-charities, clever as that is: http://blog.beeminder.com/anticharity

I feel like your answer comes from you wishing to charge money for a product (understandable obviously) more so than it comes from any actual scientific or even observational basis.

Put another way: you would say that wouldn't you.

No, if you charge toward a charity then YOU don't get to make a bunch of money. This seems stupid.

This is so awful and you a rent-seeking bad person.

[dreamdu5t]

It's not rent-seeking. They provide a service.

[fapjacks]

Oh, you mean the service they provide in being available to take money from people? That service? Hey, look, everybody! I offer that service, too!

Give me a break.
