I agree -- following is for wankers. Producing, imho, is less wankerish, but I can see your point.

There's another aspect of social media that I like to criticise, and that is how addicted people are to their 'feed.'

Like livestock, returning to the trough for their animal feed, at regular times of the day, like clockwork, people mindlessly feast their minds on theirs. Wanker feed. Cheap (get it now, pay later on attention-credit). Complete with your five mind-food-groups (dopamine, greed, anger, lust and fear).
