I've found I often read a post, start composing a reply in my head, and then just not bother.
I think many are doing this, where the discussion is had internally, but not a "real" discussion. Where does it lead, other than a higher risk of doubling down on already held thoughts?
Either we've worked out that it's manipulated and pointless or we're each spending more time on different, competing sites.
Both I suspect - the sites that are just consume with little thought probably do okay - The "cute hair/ dress/ bag" kind of stuff.
