This was inspired by a short discussion on Twitter between mperham and patio11 last weekend.[1] The basic app works great right now but I haven't put the billing code in quite yet. If you're interested, sign up for the list[2] and I'll send you an invite (with a discount) when it's ready to go.
Love the simple site and focus. I've been working on a similar project focusing more on visual diffing, but haven't been able to launch yet. Still building the server infrastructure, product focus, and working out the billing.
