The "just google it" mantra has probably held back quite a lot of interesting conversations and debate
I've always been a "lurker" on all platforms and communities because when I do have a question or would like to contribute my first thought has become:
Actually, let me google it first
In which case I'll usually have some answer. Usually it isn't a complete answer but enough for me to not want to share my question anymore.
Something I've noticed as I've shifted more of my conversations from Reddit to Discord (even before the garbage fire over at the site) is that I'm not looking up stuff as much during instant, short-form communication. Just casual conversation really is okay sometimes. I'll be trying to keep that in mind as I spend more time on Reddit alternatives.
I also have a theory that message board conversations spend as much time on opinion as they do because all the little shit has been solved now that we have esoteric information at our fingertips. Some people don't even know what it was like to be sitting around with friends all trying to figure out what 80's film you saw Robert Loggia in because you couldn't just look it up on-demand.
