I share your concerns mate. The problem is that HF19 made 2 changes, not 1.
Firstly the voting share was adjusted so it's no longer squared but a straight linear progression.
Secondly votes now cost more voting power (4x as much)
So the first change is great for minnows, amazing in fact. The second change however has a danger of turning the Steemit community into a very cliquey collection of sub-groups. You have 10 votes at full power every day, you might pick 10 friends and give them all 1 vote. You might pick your favourite creators and give them 1 vote. You're less likely now to upvote that random newbie who just made an intro post. It could become a barrier to entry for new steemians.
I did make a post about this but I won't be an ass and link it here, but it has some more rambles and details mixed in :)
I've already seen that post of yours mate, it was nicely written, I like it. It's too bad I haven't made an Introduction post yet. Wonder how much I could have earned there. Haha
