Is it crazy to offer a freemium package in a "lo-fi" startup?
jdietrich: Why two free stamps per month? If someone uses your free service for three months, or six, or twelve, what are the chances that they will upgrade to a paid service? Why would this be more profitable than a plain pay-as-you-go plan with no free stamps, or one or two initial trial stamps? If I choose to sign up with one of your monthly plans, will you offer me a refund of my unused credit if I decide not to use it?
