I pick boards that are informative as well as active , in regards to buisness that is something I probably do more of on a photography board because I am a photographer. ( interpreted: regardlesss of board/poster you have to weigh the information that is given and/or take the information to another board and "field" it with others for more input.
I keep an "eye" on what people are doing/asking for because this sometimes dictates the direction of content production , I also contribute to what I can. ( interpreted: I save "look at me" - geri halliwell , for my pictures , I'm not much of a writer. )
