Like most people I buy a lot of stuff on-line. Whilst it would be great to be able to pay with Steem I don't see that happening for a long while yet, but PayPal is an established part of the web. If someone could top up my account for Steem I'd be very interested, even if they were charging 10% for it, or some other reasonable fee. I'm going to be buying music and other stuff anyway and it would be great if my activity here could fund some of that.

I'm sure there are ways to do it via Bitcoin, but that will also involve some fees and I'm looking for convenience. I'm sure a lot of others would use this too. Having it work in the other direction would also be useful. Obviously there's a level of trust, but we take that for granted with on-line transactions all the time.
Interesting article about one guy's problems with PayPal. Seems they could close your account if you opened it before you were 18. I didn't.
