Well, the first attempt at stabilizing the Bitcoin economy was BitPay.
Thanks for the summary benjamin, I did go through BitPay's website and thought they were up to something interesting, but it was lacking details about how it works beyond the few bullet points and half a page of FAQs. What is their model?
The main feature I believe we need is the ability for regular users to make payments using their ordinary money and have the gateway automatically do the conversion to bitcoins, thus increasing demand on the currency while allowing merchants to sell for bitcoins.
Bitcoincard also seems like an interesting notion, although it seems to be a bit early for it to be practical.
In your view, do you believe that the way to mainstream is through portals/gateways of this sort expanding further?
