Wittgenstein explains why discourse on the Internet sucks. And it’s not just because of your crazy uncle.

So, language is quicksand—except it’s not. Unlike the parlor tricks of the deconstructionists who bloviate about différance and traces, there clearly are rules that shouldn’t be broken and clearly ways of speaking that are blatantly incorrect, even if they change over time and admit to flexible interpretations even on a daily basis. It’s just that explicitly delineating those boundaries is extremely difficult, because language is not built up through organized, hierarchical rules but from the top down through byzantine, overlapping practices. Some things can be pinned down with practical certainty, just not in isolation and without context.
