Money is the biggest motivator. And in Steemit, once you pass a certain threshold, your content gets a fair amount of money.
Which is all good. Above all, the interaction is amazing among the community. Because the people at the bottom needs to interact - to grow.
And people at the top, interact because they find it valuable. Either way, your blog might thrive. Once it reaches a certain threshold.
Until then, build up. And if you have reached a sweet spot, go all in. Good luck...
