Lainchan did something worse, they mixed tumbler and tech otakuism.
In imageboard terminology they mixed /tech/, /g/, /a/ and whatever hidden trash cabal board parading as tumbler that era was.
Was 4chan a good idea? If you don't think so lainchan wasn't either and it was successful since it wasn't a remake but admixture, the few altchan spinoffs that emulate lainchan weren't even vary successful, replace 4chan with lainchain in this post >>759
"Inter"national imageboards have it easy, there is the baseline culture in a nationality and alot you can do with an internet admixture alone, not to mention how well that culture plays with heritage and it just works for some alot of
people, others the majority of people on altchans unrelated to here
not so much.
