I'm interested in it. If it picks up steam it has the potential to replace PayPal.

Think of Ripple like an online wallet. You can transfer any type of currency you want into and out of it at hopefully a 0% fee, and hopefully an instant transfer.

I say hopefully because exchangers tied to ripple could have a fee. Given that ACH transfers are kind of the norm and have a 0% fee usually, it should be very much possible to transfer usd from your wallet to your friend, or an online store in the future instantly using Ripple.

All everyone seems to be looking at right now is ripples (an online currency the ripple wallet supports) and comparing ripples to bitcoins. Personally, I could care less about ripples. What I'm interested in is the potential for a fee less open wallet that allows for any type of currency of my choosing.

And sure, I've got my debt card and credit card and paypal, but one online wallet that manages all of them would be really cool.
