What about Twitter?
The people I follow that are popular are always posting.. 24x7.. its a wonder they get any work done.. but they're also people that appear to love talking on the phone and chit chatting about everything.. so if you're a socialite it may work better for you...
I find both draining, but twitter more so and i'm currently takinga hiatus from FB mostly over fake news, but considering a hiatus from twitter as well.. unfortunately though twitter is the way people in my industry communicate and get news.. (devops / distributed computing)
Popularity seems like an anti-goal unless you're selling something.
