I have personally made a switch to Delta Chat, and will be e-mailing people from now on. I will be checking facebook occasionally, as I face the same issue as others in this thread: Facebook is the default communication tool in my country. However, I have told everyone I'm connected with, that I no longer have a mobile app for facebook communication on my phone, and will only respond swiftly og they use e-mail or SMS. Let's see how that goes.
