Google AppEngine announced a new pricing model and the killer is that as soon as an 'app'* costs anything it costs $9 per month. The implication to me is clearly this: never do anything small. This probably won't be a barrier to people building a business on AppEngine, they're probably planning on moving many more dollars per month than $9. But I think it will be a barrier to tinkering and creativity.
