Wikipedia: Consensus Reality

Consensus reality is an approach to answering the question “What is real?”, a philosophical question, with answers dating back millennia; it is almost invariably used to refer to human consensus reality, though there have been mentions of feline and canine consensus reality.[1] It gives a practical answer—reality is either what exists, or what we can agree by consensus seems to exist; the process has been (perhaps loosely and a bit imprecisely) characterised as “[w]hen enough people think something is true, it… takes on a life of its own.”

Information Explosion: Metcalfe's Law

Metcalfe’s law states that the value of a telecommunications network is proportional to the square of the number of connected users of the system (n2). First formulated in this form by George Gilder in 1993,[1] and attributed to Robert Metcalfe in regard to Ethernet, Metcalfe’s law was originally presented, circa 1980, not in terms of users, but rather of “compatible communicating devices” (for example, fax machines).[2]

History of Hypertext

What is hypertext? As the smallest common denominator it can be said that hypertext is text, distributed to a set of discrete sections, with referential links in between.

According to Ted Nelson, hypertext frees the author of the obligation to create sequential text. In some cases it might be more adequate to the topic to choose a form of description that is not necessarily linear or hierarchical. Complex relations are better represented by a network of associated ideas. On the other hand the reader gains autonomy over the text as she is free to decide whilst reading where to proceed in the text when a hyperlink marker shows up.

A third dimension of hypertext is the possibility to rearrange existing material according to ones personal reflections on it. A hypertext-aware computer system can be a helpful tool to support the human ability to think – Doug Engelbart would say «to augment the human intellect».
