technologies are far more efficient than Web 2.0 systems. Making better
use of network resources by using the computers and network connections of
users, P2P avoids creating bottlenecks created by centralised systems and
allows content to be published with less infrastructure, often no more
than a computer and a consumer internet connection. P2P systems do not
require the massive data centres of sites such as YouTube. The lack of
central infrastructure also comes with a lack of central control, meaning
that censorship, often a problem with privately-owned ‘communities’ that
frequently bend to private and public pressure groups and enforce
limitations on the the kinds of content they allow. Also, the lack of
large central cross-referencing databases of user information has a strong
advantage in terms of privacy.
