Posting in niches and building a community is a highly valuable approach and in time is where the consistency will come from. It takes work though and that is my point, those who have an earning expectation for this moment won't build a community around them for the next. There are very few users here currently and most don't have s great deal of available stake but, that will change. Steem is going to be empowered by niche communities in the future, investing into their creation and development now as a user is an excellent idea in my opinion.
