I think that bullshitting is just part of human nature (or at least of the current global society/ies). You just need a critical mass to see it properly. When a community/social network is small, it's either bullshit free or completely full of bullshit. When it's big enough, the bullshit quantity will converge regardless the initial value.
To what should I answer? To what people you know do on Twitter? I stand by my opinion: the platform doesn't have a word in the bullshitting level, unless it strictly moderates the content in a way that would be basically dictatorial.
