It's mostly fantastic. Highly recommended. The sky does not fall.
Did nothing to curb the addition, however. I still check incessantly. Just unprompted.
Also, turn your read receipts on. It's a form of honesty that helps people form a realistic picture of what's going on with you (that sometimes you can see something, but don't have the time/energy/care to reply). I find this casual boundary to be healthy. It also pressures you to be more courteous to people where it counts (you can ignore this person, but they'll know. act accordingly)
The only thing that makes noise is if someone calls me.
I also don't use any "social" media really. I spend 10 mins here on HN every morning and night though.
