I think you ought to be making at least ten times as many comments as posts.
I agree with this. Community after all is built through social interaction. Not didactic broadcasts.
Perhaps one trick is to finish a post with an open question. That way it prompts that reader to feel like responding. What do you think?
I see what you did there ;) Open questions invite a response.
I asked one guy why he hardly ever commented and he said "I'm a content creator!". He's still not making much.
Exactly, interfaction and a few comments builds a community spirit and drives better engagement. This in turn will lead to people making more from their Hive experience.
