I think the pricing scheme is way too clumsy. The Amon and Amon Plus seem to map to two different kinds of web apps: hobby, and mission critical. There's a huge gap between the two plans. You're basically ignoring the users between the two levels by insisting that anyone who needs more than basic service get the super deluxe model.

The pricing scheme drastically needs a change. The free level is fine, but there needs to be at least onepaid intermediate levels: 2 apps, with features between free and plus. Why? If a developer is doing 1 hobby web app and wants to take it to the next level, a 2-app plan will both provide support for their current app and allow breathing room in case they want to go for a second.

As a web app developer myself, I would not pay for the Amon Plus plan. I have 1 web app running on AppFog. I don't need to pay for unlimited servers and unlimited apps. I would pay for basic support, but paid basic support is not available in the two tiers offered.
