I would say few members of this forum are real "Developers", and most are hobbyist, users/super users like me. So most of these people are not looking to hire someone but build it themselves. Most of people seem to building for themselves, friend, church group, book club, kid's soccer league, dart league, etc. I do not see many people working to build something that big for a business that needs a developer. Rarely.

So I just think this is the opposite of a place where people are coming for hiring someone. They are coming to "feel more powerful" themselves.
Now on the flip-side, I have seen those posts like
"I am a pediatrician/ veterinarian / accountant / entrepreneur / (insert important busy person here) etc and have spent many hours building this for my small buisiness."
Those I have to question if they understand the value of time, and wonder why not hire someone. But I think it is the same for these people too. Its that sense of building and accomplishing things.
