I would use the fuck out of ripple for self issued credit, but ripples work on the scarcity model. If ripples where free and unlimited it work well for me.
XRP is the only asset on Ripple that works this way, and it has to because it's used to pay transaction fees and there's no known way to support unlimited transactions.
Of course that destroys their business model. The ripple team thinks they will get paid by the valuation going up for ripple. How about getting paid by providing a valuable service?
If we followed that model, we'd either have a lot less money to spend on development and integration or we'd have to charge for lots of things we can do for free using the model we've chosen. We set things up the way we did because that was what we believed was best. The market will decide whether we made good decisions or not. If we chose wrong, we will lose to those who make better choices. Worst case, the world gets a payment system that's even better than Ripple. I can live with that.
Well I will wait on that better system then.. good luck.
Define a ripple, take the hard limit off, allow people to create them when they issue and asset, require that they be redeemable, fixed.
