> Twitter is a cesspool of useless noise and ego
That's what Reddit has been, in my humble opinion, since I've started using it - since 2005.
Country subs, most of the most famous subs, pretty much everywhere - it's just a lot of nonsensical quips, flame wars, karma hoarding (Reddit has a different unparliamentary word for that starting with "w"), the ubiquitous herd-mentality - one comment (mostly a "quip" reply) that came early gets bigger and bigger and everything else takes naturally a back seat, your very genuine doubts, points getting downvotted to oblivion sometimes for no apparent reason. It's a big list I believe.
Yes, there are subs which are good and can actually mean some meaningful interaction but it's not very proper to always call reddit right or better than Twitter or any other medium by referring to those few subs like /r/TrueFilm [0], then there's /r/DepthHub and /r/TrueReddit which are supposed to be "good" reddit but there are just no interactive discussions there they usually connect to popular comments usually highly gilded and popular ones.
Initially /r/ImAA seemed promising but that's just a PR board or been reduced to it. No, candid conversation (and I don't mean masala and gossip and scandal) is as rare as it gets. Places like /r/AskHistorians are as difficult to start participating that you just give up in the first go - it doesn't at all encourage participation; you don't know who you will flare up with your seemingly innocuous comment. At many places Reddit makes being a newbie almomst a crime and then there's instant justive too.
Reddit, for me, is mostly about what I have mentioned above and mod ego, monopoloy and knee jerk reactions and botached interventions by admins if at all they do. Abuse goes unchecked which is compounded by the herd-mentality. Like really unchecked and it's a hell for female users. The famous Reddit saying goes like "There are no girls on the Internet" and whenever a user is indentified as one it's almost unlivable there for them. And then there's doxxing.
Reddit sometimes works for just a lurker whenever I need something and it has it. Or a casual browsing for few minutes here and there.
