4chan, despite all its vileness, has convinced me of the necessity to maintain as much unrestrained human freedom in (at least) some quarters of the Internet as is possible. Such freedom seems so essential to Internet culture that, in my opinion, it must be protected.
> 4chan, despite all its vileness, has convinced me of the necessity to maintain as much unrestrained human freedom ... Can you provide an example of something valuable you found on 4chan/8chan that could not be found on a site with less "vileness"?

I have a 4 year old daughter now who LOVES Minecraft. And personally, it's been valuable to me, and I am utterly convinced that had Minecraft not been developed in its earliest days on 4chan, it might not have gotten to where it is today.
*Small shoutout also to Katawa Shojo - also made with lots of input from 4chan, which turned out to be quite a compleling VN game.
What has 4chan done lately that is valuable? That I couldn't tell you.
