>the deluge and cacophony of notifications, emails, texts and phone calls I imagine we are all getting inundated with everyday with increasing entropy and volume.
I don't think I experience this?
My general strategy is to disable all notifications for Android apps except messaging. Phone is always on silent, so I don't get random calls.
I definitely get a lot of crap emails though - so many where the company creates a new marketing list and subscribes you to it. You can unsubscribe from that one specifically but not future ones.
Dropbox did a particularly spammy thing recently. In the same week they emailed me to say I was running out of space and I needed to buy more, and then also they emailed to say I had space that I wasn't making the most of, and wouldn't I like to try these other features?
