It's not because everybody is using it, that the tools is ok. It's like everybody is playing LoL, are LoL great? Doubt so, but it's like playing it because everybody play it.

You have mail, if people can't contact you without facebook, then the problem is not you, but the users. Like for example a friends won't join discord because it own is own chat server, yes like I want a tool by friends. I just ignore him he always wanted that I adopt his solution.

It's a combination of people being there AND having a bunch of related tools (mainly of importance to me, groups, events and comments for events). E-Mail is inconvenient for most things I use messenger for.
