What sucks about group chats? i.e. email 'reply all' and whatsapp groups.

What sucks about big conversations with lots of participants?

This comes from a place of deep frustration on my part having tried to organise a few large group holidays lately via Messenger.

Email conversations with lots of people are not something I have to handle very often so I am keen to learn more about the pain points you guys might have with those 'reply all' situations.

We are working on a product called Plum Mail and trying to focus on fixing group chat at the moment.

Cheers
