Indeed, language is a powerful tool. It is a heat-seeking missile and a shield at the same time.
I think the development of social media into a chaotic, free wheeling, uncontrollable network will be the true public domain in the future.
That is why the internet (the great social media) is so great. Unlike other mediums of exchange (like currency) it is decentralised and (largely) unregulated, allowing such conversations as this to occur.
The way I see the internet is that it is almost like your free market of curious discussion...
...it is the thing people like us like as a rebellion against a mass media that expels spin.
