Thanks for sharing your view on the SBD. I share your thoughts and it leaves always the feeling that the voting system of steem is overengineered. Just to many variables and of cource the system produces what it is incentivizing.

I think to a certain degree people with major steem investments always have also the long term perspective (I hope) so they probably don‘t want to spend their full 10 votes on own post (and hopefully not creating therefore spam posts which unfortunately happened also). But definitely it make sense to upvote own content. What I am doing at least is upvoting my own post as late as possible what increases curation rewards for all upvoting my posts. So kind of win-win.
