I learned so much over the years abusing Cunningham’s.
Could have a presentation for the C-suite for a major company, post some tenuous claim related to what I intended to present on, and have people with PhDs in the subject citing papers correcting me with nuances that would make it into the final presentation.
It’s one of the key things I miss about Reddit. The scale of Lemmy just doesn’t have the same rate and quality of expertise jumping in to correct random things as a site with 100x the users.
The major problem with reddit is that you could never really trust the credentials of the person you were talking to. They might have been PhDs or they might have been 13 year olds who just learned to Google. It amazes me how many times I saw a highly upvoted comment posted about a subject that I knew a lot about, but was just so blatantly wrong.
To be fair this is not a Reddit thing and it can be found in the fediverse too. I can remember some of such situations where a person just posted wrong stuff but in a very confident way. I was able to prove him wrong later but nobody cared anymore.
