Making Money from Open-Source Software

Continuing as I did before, just writing a lot of code and trying to create an OSS project out of it would eat up all my time (and money). Instead, our support staff consists of decided support engineers and the core team that builds RavenDB. For example, writing an error message that will explain some issue to the user matters, because it would reduce the time an engineer spends on the phone troubleshooting (not fun) and increases the amount of time they can sling code around (fun).
