Why I don't use Twitter [View all]
It's a matter of controlling what I can control, and getting information that *I* choose, while being aware of alternate viewpoints.
To that extent, I use DU as a news aggregator of everything non-techie, and Hacker News (https://news.ycombinator.com/newest) as an aggregator of damn near everything techie, plus the chance to glance at one-line summaries of stuff that the Ayn Rand crowd posts.
Both are actually moderated to keep outrageous and vile bullshit out!
WHY DO I DO THIS?
Because life is all about actions.
In life, PULL WORKS, PUSH DOESN'T
Life is like a rope. Pushing on a rope moves nothing but a short piece of rope.
That is like arguing with idiots. The best you can do is "run up some numbers".
By associating with like-minded and GOOD people, you can have some influence in order to make things better.
That would include (hopefully) friends, family, work colleagues, fellow hobbyists and so on.
Unlike the binary "It's you or me" world of Twitter, YOU STAND A CHANCE of making positive change.
All advertising-supported sites are about quantity, and screw quality.
Plus, I really choose to keep garbage out of my brain. Just being aware of stuff, in a "Wikipedia" kind of way, is enough to help me do positive things.
No muck-diving for me.

Consider this:
CALL, TEXT, EMAIL YOUR GOOD FRIENDS

Friends Ask Friends to Vote

First, make a list of your people: friends, family, and community groups you are a part of; people you see regularly; and people you work with. Next, identify who on that list aligns with our ACLU values, but may not always vote. Then, let them know theres an important election coming up and help them make a plan to vote (when, where, and how). Call them if you usually call them, text them if you typically text them, or talk to them when you see them next. Well also provide you with a conversation guide

HAVE A CONVERSATION,

NOT A TOMATO (OR OTHER) HURLING CONTEST!
PULL (willing) people towards you
This works in life, not just politics.

Thinking about this, I guess that DU and Hacker News are PROXIES that let me know what's going on, actually ban horrific and vile content, and let me choose what to explore, and with whom to engage.
Keeps the clutter down.
