The most grim part about this post is that it is not even a recent post. This is from over 4 years ago and it has not become any less relevant in that lapse.

I want to disagree with the OP a little, or maybe even agree with additional terms.
Where I disagree: I think you can find some interesting content on 4chan, but it will be amidst piles of garbage.
Where I agree: doing something else is probably better than browsing 4chan, OR Reddit, OR Twitter, of like 90% of the internet.
