24chan 

24chan is a chan that started as a refugee for 4chan trolls who want a cancer free board.

Friend 1: If you are sick of the cancer that is spreading like herpes go to 24chan.org
Friend 2: What, isn't that just like 4chan.org?
Friend 1: No, gtfo and troll moar.

2chan 

The granddaddy of Japanese message boards, full of anonymous users who generally are fairly civil and not totally creepy. See antonym: 4chan

"Check out this cute cat pic from 2chan!"

"Kawaii!"

"Check out this pic from 4chan!"

"WTF is your problem!"

2chan 

The originals of board websites, prior to it, the creator of 2chan is now the CEO of 4chan, and it is not something like 4chan or 8chan with the people on there being fucked up and full of shit, the people on 2chan are actually peaceful and not creepy.

Look at this cute cat I found on the street, I found this on 2chan!

So kawaii!
¯\_(ツ)_/¯
