This is pretty similar to my own way of managing communications. My main concern is that this way of communicating is endangered due to mobile and walled gardens. Maybe I'm just a dinosaur. XMPP and IRC don't seem very mobile-friendly, or at least mobile connections aren't reliable enough for them and rely on push notifications. The mobile clients (that I've tried) seem weak. Each new "innovative" communication requires yet another app I need to download and check, with communications trapped inside a proprietary client controlled by a company.
