Well I don't think most of my posts are of the heart... probably more of the mind but you make a good point. Hehe. When the price of Steem skyrockets again I'm sure more people will sign up or come back.
Since last year I just post whatever I fancy. Also I do posts that can help promote my real estate, health products and art business too.
Price always brings people back, the problem for them is that they are motivated by a narrow use of steem and one that isn't omni-present.
We should all write about what we want, but if looking for outcome, consider our delivery.
