Outside, hopefully.

Snark aside, 4chan was once hugely influential to internet culture and humor, but that era was long, long, long ago. When 4chan became the breeding ground for the alt-right, that thoroughly infected the site so badly that everyone else was driven off. There is nothing of value left on that site, and its death is a net positive for the world.

Of course other imageboards still exist, but I don’t think any of them will ever be as big as 4chan was. I hope that none of them become that big.
