>>57418>Maybe imageboard culture is dead forever.
There's no "maybe" about it. Alt-chans are all dead/dying. Any new ones that get made end up gone in a few months. Much like forums, they're largely just relics of the 2000s internet.
Back in the day, say 14 years ago, most imageboard users mainly only posted on imageboards. Those who used an alt-chan made it their home. But now most imageboard users grew up on social media, and they mainly use twitter, discord, reddit, snapchat, facebook or whatever and just use imageboards (mainly just 4chan) as a dumping grounds to shitpost, troll and post things they otherwise don't want attached to their identity. Since they only see imageboards as dumping grounds they rarely ever even find an alt-chan and if they do they just see it as an easy place to troll and get easy replies.
Imageboard culture thrived when the internet was predominantly nerdy male outcasts and normalfags only used it for emailing and chatting with people they already knew in real life. But those days are long gone, ergo why imageboard culture is dead, and dead forever.
