You're not wrong about this, but in this sites case, profit is not the motive. It's just a group of people with similar interests it seems. Are we trying to get big or are we just trying to share info with like-minded folk?

I know that not all of the stuff here I'm interested in, but I don't mind having things thrown my way that don't interest me. I've actually come across stuff here that have sparked interest in things I've never known about previously. Just saying.
