I thought I'd made myself clear in the original comment, but I'll try again: the issue with these sites is not the "channel"/imageboard format itself, it produces great results at a certain population size. The issue is lax moderation and the greater proportion of highly active bad actors when the site reaches a certain critical mass of users. To generalize your experiences on large, less niche sites like 4chan is to miss out on some of the smaller gems out there that share the imageboard format.
