Just engaging with all the devices is a job in itself. Its very tough to focus.

I keep all social media & news apps in a tablet that I refer to as the "time-killer". Controlling the alerts is a losing game. So, I just put all in a separate device. Even with browser, I have a separate profile that I use for HN & reddit.

Even my phone is silent most of the times. I wish there was a answering machine app, so I can respond to calls at my convenience. In my circle, we actually just voice message via whatsapp, so no one is disturbed and can respond at a convenient time.
