I hate the word ‘Consumer’ or I mockingly call it ‘CONSOOMER’. Because that’s to imply everyone in the world is just cattle, but with wallets. We’re no longer customers. We’re consumers now. And a consumer’s purpose is to consume shit, whatever is put out there. Got money? Shut up and consume, it’s what corporate interests and capitalism itself thrive on. Consume and consume.
Those are one-way communication channels though, engagement sounds like a pretty accurate way to describe the interaction you can have on social platforms, you show interest in some content and make that interest public by liking, sharing, etc.
