Great Information Post ... Upvote and Resteemed
Improvent that Im mostly looking after on steem right now is private messages between users.
Lack of this forces me to leave the platform when I need to talk to someone from here and I have to ask publicly for someone details for contact. And either mine or theirs data is being revealed while doing so.

This is a major flaw.
Also some sort of notification, when somebody answered me would be useful.
Those things look tiny at first, but once introduced they prove to be very convenient and major improvements.

I know this from experience from other websites, so its not just a theory.
