You raise some good concerns, but are you thinking the Steemit team are unaware of them?

I see a couple options for you:

Join their team and contribute
Submit proposals through the proper channels (Slack, Github, #proposals, etc)
Leave the site and comeback when you feel it has matured enough for you to enjoy it.
I've seen a lot of posts like this and, to me, they seem to disregard how difficult something like this is to accomplish. As a developer, I have great respect for the speed at which they are moving and the quality of the changes they are making. I'm looking at the code diffs of the releases they are putting out and they seem to be making some really good improvements.

Think of this like the early Internet. Email used to be through SMTP commands typed in by hand on a console.

Let's give them a few weeks and months and see where things are there before we get out the pitchforks. :)
