Most ordinary people these days want a slick user interface with lots of smooth edges, curves, and plain colors with a corporate memphis art style. Importantly, they want something that feeds their narcissism and allows them to express their identity through an avatar and a bunch of friends with all this including their irl info. Lastly, they are actually profitable tech companies whereas imageboards often run at a loss and are just community projects, so there's no way you'd get financing for an internet forum to compete with social media. >>137> I don't think there'll be a mainstream internet forum, ever,
2channel, the grandaddy of all chan sites, was as mainstream as Reddit in Japan and the country's biggest internet community until it split in 2014. At one time, it was the biggest site on the internet and it was an anonymous textboard/BBS. >>144
All I can think of is an anonymous version of Reddit with the kind of attitude to moderation you see on some of the better imageboards. But it would still have to have that memphis art style and have the look and feel of a Silicone Valley tech company.
I doubt imageboards or internet forums will ever be as big as they used to be and anonymous 2chan/4chan type sites are on the way out. Vast majority of gen Z just don't trust those places and see them negatively.
