Internet communication can be tricky: it is based on a split of body and mind - the body is in one geographical location, but the mind at another, and to boot, this split is quite expensive (one has to have a working computer, internet connection etc.).
But we cannot be infinitely satisfied with enduring such a split. I think the ideal would be to have both the body and the mind in the same geographical location.
Consider: IRL, the people who participate in the discussions here would most likely have no avenue to actually meet and discuss things in one geographical location. And even if we did, the reality of our everyday lives would heavily influence the topics and the way we engage in them.
Compensating for it with online forums gives the exchanges a sense of fakeness, as if it was something unreal or stolen, something we cannot actually afford. As if these discussions are a mere philosophical leisure, with no real value or relevance. Which, I am sure, is reflected in the way we go about discussing and the topics we discuss. Intellectual masturbations.
