Yeah, it’s awful for that. I do use it from time to time, but have reached a point where I’m asking myself “Who is this for? Why am I posting these photos? For myself? Do other people actually care?”.
Watershed moment was when I got more likes for a photo of a dildo stuck to a moped than I did for the post announcing my first born child. Got to take it all with a pinch of salt really.
I use Slack at work all the time. Have a remote team in Serbia so we rely on it.
For friends and family - Whatsapp, although why - WHY - does everything in life need a f**king Whatsapp group these days. Nothing like getting the ‘You have been added to the group Bank Holiday Fun!’ followed by 100s of messages then everyone leaving the group.
