I use it as shorthand for “this is received wisdom that you likely haven’t thought about critically and are just saying because it tends to please the reddit hive mind”.
Which is something I did indeed want to say in addition to my actual point.

I was thinking last night how I'm biased towards gleaning information from sites I avoid without having to visit them :)
