Please force SSL/TLS on the accounts page if not everywhere (should be everywhere)...You're currently sending Stripe payments over http
I have something in mind for this, but haven't gotten around to implementing it yet. Full SSL is coming.
There's also a Go (golang) port:
https://github.com/cactus/go-camo
I'm currently using go-camo in my own feed reader and have experienced some flakiness (images fail to load sometimes).
(Also, nice work!)
I thought Stripe blocked that specifically.
