Focus on curation and content generation aspect. Engage with people. If your focus is on money you will prefer a specific pattern which might be working for people. however if you focus on engagement, curation and generation you will have satisfaction that you are doing something good and on sides you are making money.
I seriously advice people don't look at any of these options as full time money making options. If you do want to do that then look at every possible option to get more out of it and you might have to invest some to gain large. But the other way would be to just focus on good content and consistent content.
