For example, you can hopefully recognize when someone is intentionally posting something bad or offensive (like the bad cooking videos we mentioned in the Virality chapter, or an intentionally offensive statement) in an attempt to get people to respond and spread their content. Then you can decide how you want to engage (if at all) given how they are trying to spread their content.
I've noticed every time something irks me on a platform I immediately think back to the high-friction low-friction concept. Perhaps this is a lasting takeaway of this class.
