And this is it in a nutshell really...no one is going to make a dime on this site because it is not properly curated or reviewed.
In order for a collective like this to work, *ALL* the artwork has to be top notch...it is competing with decent to good work that amateur camera owners have spewed out onto the internet for years now that is free....Freetography folks...."I Heart Sharing photos because I get nice comments" equals free!
By the way, this...?....would not even be put on a wall if free....

Yep, that is reality. I am starting to really pull in nice monthly figures off of my black and white work and I don't even have a public website instead preferring to keep it out of the eyes of amateur camera owners and just deal with interior decorators, high end hotel and resort chains and galleries directly. I expect to be able to stop doing commercial work in about 5 years. But what you, I or other folks say on here simply does not matter to some...they refuse to accept reality.
I gotta log out...the amount that people tend to BS each other with on this topic or any topic of earning money in photography just gets me too wound up...
