I'll pay someone 10-30 bucks if they recreate ifttt with a pinboard model. Keep it simple stupid, fairly cheap, and charge extra if you want to do things like SMS/Voice/things that require constant notification.
It's your lucky day! Make a detailed list of what you would want from such a service, divided into levels, and indicate how much you would pay for each level. Place the list here, or email it to me, and I'll try to build your ultimate ifttt clone. I like pinboard and ifttt, but I see ifttt as struggling to transition to a paying model because they are spending way too much time, money and energy supporting a large user base for free.
