How can thoughts and symbols representing thoughts become Social System? Redux

Perhaps through tags and folksonomies.

Adrian Chan thinks so too. More here.

BTW his bottom line statement

"just as we recognize the value in the diversity of cultures and ecosystems, diversity in tag cultures, as vernaculars of a sort, might help to preserve value. Preserving the state of a culture, also, might be worth looking into, if only to lay down time capsules!"

sounded like "Meanwhile, culture as we know it now may no longer be the same as our children will know it tomorrow. Whatever direction it will ultimately take, preserving culture is a good place to start."
