I had the same experience about a week ago. I was posting in steemit and seeing nothing. I finally found sportstalk and saw that my posts were reaching an audience(and were accruing sports tokens). Similar thing with D-Tube.
Weird thing I noticed. I can post a weekly article covering the same topic on the same day at the same time and get completely different results. I don't care about sports tokens so much(they will come with good content), but I'm curious if anyone has suggestions for increasing engagement.
That just prove my experience is the same with you guys. Curation in Steemit still is a problem. Newsteem has somehow failed. Dao is just a form of milking from Developers. When I joined sportstalk, its the first time I received decent rewards.
