X is where the news is these days. Also, there are some technical people I follow.
Absolutely, it’s up to you to limit whom you follow to use it effectively.
“The Liberty Daily” is a great site filled with lots of news links. The headlines at times do sound like Mark Levine insulting people at times.
As for X, I find it hard to follow anything as it seems to be people throwing stuff on a wall and hoping for views.
