It is like fishing. You can't expect to get a bite. Just do your thing and be thankful when one does take a bite. It looks like THIS post of yours is bringing in a good haul.

There are a lot of good posts that don't get votes or good payouts. I think a lot of it is timing, and whether your post happened to be of interest to anyone with decent steem power at a given time. I'd expect this to spread out more as MORE people get significant steem power as that will broaden the interests. Yet it is still possible even then for a good post to fail. Sunday night was pretty SLOW for everyone.
