You can also try to do what i call niche cross diversification. A form of niche that cuts across relative niches, it helps to expand your target audience and opens you to more visibility. Also it helps to build your flexibility. Remember, if steemit goes today, you need to have developed yourself enough to stand alone to do the passion you claim to have on steemit, this should be the keynote, development of oneself in contribution of value, just as @empato365 has said. Glad steemit is not going anywhere, now lets go on to that writing my man!
