4chan unironically. The niche hobby boards are a great way to get immersed in a hobby. Discussion feels more genuine and natural compared to Reddit where dumb, witty joke comments get upvoted to the top. No accounts or reputation bullshit, comments stand by their own merits. It's like going back to how the internet was 20 years ago.

I'd like it too, but it's too NSFW for me, also, too much anime girl.
