Communities confusion.

Ok, folks! I confess that I was skeptical communities will ever happen. Maybe I'm just a bitter old man..maybe i've been hurt before by Steemit INC but..I didn't take it any seriously than anything else cause I didn't think it will actually be implemented.
I WAS WRONG!

Ok.

But now. I am not sure what to do. Can anyone direct me to some good information or just comment here?
What should I do with my posts? I mostly post photography with some personal sprinkled in. Is OCD the right place to me? What is even a "right place" in the context of communities?

I generally want to have a bigger audience for my photography posts, I want to make more $$$ for my posts and generally just interact with ok people.

Help.
Thank you.
