Excellent comments, you have a new follower :)
a.) They voted more often with their insane amount of delegated SP that was given to them for that exact purpose
They do like to keep the vote power % above 95% I see, so this could be achieved by reducing the size of the votes I guess
b.) that they would do a better curation job
I think everyone bar @exyle has said this - I have, they dont vote me every time - just like here!
I have been trying to establish a daily Steemit news show, covering the happenings on Steemit, and introducing new Steemians every day, and the quality doesn't change, nor my format or thumbnails, but the upvotes from Dtube are so rando! It leaves me bewildered to say the least! I can definitely see where people get frustrated. But all in all, it's still the best shot at getting at least a couple of good upvotes a week!
I will have to take a look :)
The team manually curate, as apposed to @utopian-io for example, who approve/reject, and then all the approved go into a pot in which submission category, and number of submissions are calculated to return a voting weight which is applied to each individual post.
With manual curation, it's not going to be perfect, and so when you are missed for producing the same quality it is frustrating - I'm totally with you having been missed on my last 2 vlogs.
They are still however, a far better prospect than anything else above, and i'll continue to vlog as I hope you will too.
Now, time to go check your Steemit show :D
