Yeah and this implies that people by and large still aren't tech savvy (enough). This is very unfortunate as we have to use the software most people are wiling to tolerate. Ironically, in most of my use cases e-mail is the best solution for communication. It is based on widely accepted protocols [there is an abundance of e-mail clients you can choose from without fearing compatibility issues], delivery is (most of the time) almost instant and it is up to you which provider you use (or you can even host an e-mail server yourself). It's also good concerning encryption in that you can agree with each of your contacts whether or not you want to use some form of it. In contrast, messenger like Facebook don't give you a choice and OTR is not something everyone is willing to learn about.
