I like to think some of my posts are for my readers and others are for me. I have a decent idea of which posts will get more attention.
It is not just about interesting. It is about what others agree with. I noticed some posts that earn more rewards, despite taking just as much effort as 'boring posts'. Tagging newsteem now and writing about how awesome Steem is gets votes, but writing about this every day gets boring.
People need to diversify and experiment. Or the audience moves on. Truely creative stuff cannot be pumped out daily, especially videos.
I rarely watch videos on Steem, because it is usually just people reading their blog or worse rambling. Maybe they are podcasts, but again, haven't found a good on I want to listen to regularly.
