Have you found any social medium on internet that actually empowers honesty?
We weren't discussing truth, but honesty. Someone deluded can still be honest given what they (falsely) believe.
Besides, I wrote about how there are multiple incentives to lie, and a platform were you're not having a financial interest in what you write, removes some big ones. Doesn't mean something like 4chan doesn't have others.
Still, I'd expect to find a homest to god personal confession in 4chan or Reddit way more than on LinkedIn.
