This is a good post, but I have one bone to pick: After talking a bit, this person starts giving me grief for working in a closed source solution. I asked him what database solution he used. He happened to use a GPL licensed Open-Source database on which the company that owns the trademark has all the commits. It’s that kind of read only Open-Source. In all fairness, it's a forkable kind of open-source; think the Jenkins / Hudson split. (When you're building your company or product on something completely closed-source, you're kinda screwed if they go away.)
