Services I want on Steem

There are a lot of services I would like to be on steem.

I am searching for them, but they seem unable to find.

Is there

• Anything like an instagram on steem?
• A Q/A network similar to stackoverflow?
• A shop for digital goods/ games / software tools (App store/ google play/ Steam equivalent)?

They seem entirely possible, in my view.
Steem already has a medium, an youtube and a twitch equivalents after all.

How about you?

What services do you miss on steem platform?
