10. compact definition? [O’Reilly]
I said I'm not fond of definitions, but I woke up this morning
with the start of one in my head: Web 2.0 is the network as
platform, spanning all connected devices; Web 2.0
applications are those that make the most of the intrinsic
advantages of that platform: delivering software as a
continually-updated service that gets better the more people
use it, consuming and remixing data from multiple sources,
including individual users, while providing their own data and
services in a form that allows remixing by others, creating
network effects through an "architecture of participation," and
going beyond the page metaphor of Web 1.0 to deliver rich
user experiences.

12. Cluetrain Manifesto
http://www.cluetrain.com/book/95-theses.html
# Markets are conversations.
# Markets consist of human beings, not demographic
sectors.
# Conversations among human beings sound human. They
are conducted in a human voice.
# Whether delivering information, opinions, perspectives,
dissenting arguments or humorous asides, the human
voice is typically open, natural, uncontrived.
# People recognize each other as such from the sound of
this voice.
# The Internet is enabling conversations among human
beings that were simply not possible in the era of mass
media
