I'd be a complete and utter ass hat if I didn't put a brief explanation to why I downvoted. I've done this on all other posts I've downvoted since HF21/22.
I've always maintained that trending is the first place new people are most likely to make a judgement about steem. The dogshit trending we had has improved since HF21/22 but there is a big hurdle to get over for steem to start bringing more new people to the platform and that is the steem-centric content that dominates trending.
I showed this post to my girlfriend, who is reasonably technically proficient, and I said to her '"tell me honestly what you think about this post? Would it interest you and encourage you to join this platform?" To cut a long story short, she didn't understand a word of it and said it put her off immediately. I barely understand about 30% of what this post is talking about and I've been on steem 2 years.
This is the only reason why I downvoted it. I think everyone needs to be judged to the same standards, and I'd ask the same question of my better half about any steem-centric content that was boosted to this extent. By the way, I have explained to her much of how steem works to my level of understanding so she isn't clueless.
What I mentioned above isn't the only consideration I have when looking at trending content and thinking about using a downvote, my biggest consideration is the boosted shit posts. But they are getting less and less, which I think everyone can agree is a very good thing :)
Agree with most if not all of what you said there.
