180 days release date is far to long.
I don't think we should be trying to emulate PayPal. Paypal has it's benefits but I don't think they should be implemented with bitcoin. I'm sure there will be payment processors that you can use that will be just like PP, though I hear they're looking into implementing bitcoin but not sure in what capacity.
Sarcasm does not flow through the internet.
Use /s or just say something like "We should
totally implement an
awesome system , not unlike the one owned by Paypal"
