I donated here via pay pal. It would be interesting to know how much they got from that source.
I had the same thought, would be good to know how much was "really" pledged, including the paypal money that is not shown through Kickstarter.
A possible way to include paypal to Kickstarter would be to have a KS paypal account. All money that is transferred there would be included into a successful KS, or transferred back to the people if KS fails. No reason why this shouldn't work. Gotta write KS a mail.
That's an interesting take on it. Here in the UK everyone has a debit and/or credit card. I agree that I dislike credit cards. However, I can't imagine not having a debit card. I payed Kickstarter with my debit card.
A credit card usually comes with additional monthly fee in Germany, which might be why many don't have one. There may be CC providers that charge no fee, but I don't know how trustworthy these are (I made my CC at my bank, which part of my bank account now).
I did it because of a single KS campaign back then, but found it useful to buy games from GoG.com and a couple of Steam games. Though, I think I could have used paypal with GoG.
