What list of users do you wish existed?

This is a picture from early fall last year up near Mount Nebo, on the Nebo loop highway.

THE ACTUAL SUBJECT ON THE POST

But the post is about getting feedback from people

THEME: IF a certain Steem Interface were to create a certain cool new feature that helped connect people, identify people by interests, help content discovery etc etc...
... Well if that sort of hypothetical feature existed what kind of list would you wish existed?

PRIVATE LISTS

A while back https://steempeak.com/ made private organizable lists.
I know I've loved creating them and visiting the feeds for those users from time to time.

I've had people ask for some of my lists... well...

PUBLIC LISTS

What if there was a way for users to create specially curated and thematic lists of users?
And perhaps for them to have tons of extra functionality...

Well tell us what kinds of lists you're most interested in.

LET'S PRETEND

Let's pretend a certain site has something up their sleeves
... and let's pretend someone who's willing to create/curate an awesome list right now get's Early Free Access

Let's play with that idea and tell me if you're interested in having a creative list and keeping it up to date.
Or just tell us what kind of list of users do you wish existed.
