Generally good thinking, but few "real world" notes

A) you first need to run the service to get any customers

B) this might take long

C) you maybe don't want / can't get VC money at this stage

D) you maybe are not the most advanced dev who can properly utilitize s3 from I/O perspective, getting you to higher costs than possible

E) there might be a time period between introducing the service and getting traction which yields enough feedback, so you can start adding more business features

F) when you are burning your own money, you are more senstive to the cost side - which is not ultimately wrong

Just my 2c
