I aim to clap 7 or 8 times for something I really like. It’s just a figure I’ve chosen arbitrarily. (Holding down the “button” — I use a trackpad — doesn’t seem to work for me, so to give maximum claps I’d have to tap 50 times.) Because of my relative parsimony with applause, my previous recommends have presumably been devalued to one seventh of their previous worth, not to one fiftieth. Resetting the clock as you describe wasn’t a bad idea but I suspect that the listicles will rise inexorably again. I described them elsewhere as an “evolutionary adaptation”, which get upvoted, recommended and thumbed-up almost irresistably.
