This is the living proof that the "web app market" is really stratified and the value perception within each customer group varies immensely. Who would tell that a 4 year old scope of features could keep a product alive? Who could possible agree that a system that supports thousands of accounts could survive without "hygienical" processes like OS/DB maintenance, bug fixing etc.? Who could imagine a product with a growing adoption/acceptance not having paid options included as plans to leverage revenue in the long run? Uff, this is all mind bogging to me. Congrats to the author though, this is an incredible story!
