Hi @mariusfebruary,
First things first. Of late, Whale Steemians like you, but very few, are taking a step forward, that too, very broadly, to develop this Steem community, by helping planktons, minnows and small fishes.
As said by many Venerable Steemians, our Steem community is undergoing a favorable shift towards prosperity and this is what is needed at this critical juncture to make #Steemit a force to reckon with!
"Should I base my upvotes solely on the quality of the posts and thereby support people who already know how to produce?"
To save our Steemit, we need to support "Quality posts" and your upvotes must be SOLELY based on this single criteria. Every single upvote is invaluable and so this criteria must never be sidelined come whatever may. Please don't think whether you're are upvoting known or unknown, but also encourage with your upvotes to those new entrants to Steemit who are posting quality content.
"Should I assign some of the upvotes to people to encourage them to become great authors?"
Definitely Sir, you must.
This is my humble opinion, @mariusfebruary.
