1. Censorship resistant resource access.

Govts turn off the internet. (Egypt 2014). Use of peer to peer resource access allows N geographically proximate users accesss to the same file or resources, assuming at least one peer has downloaded them already, for everyone else to get it through them.

2. Broken Links.

The original tenets of the web are violated daily: Links to corporate-supplied services and resources are taken down when censored or when that service goes down or when that corporate goes out of business, or when a hitherto free resource is hidden behind a paywall. Burning books anyone?

3. Verifiability.

PSR-2 says...

* Indentation: 4 spaces
* Newline: UNIX LF
* End of line: No whitespace
* End of file: Single newline (Why? Historical tooling reasons)

Debugging:

"Never, ever assume you think you know where a bug comes from". I have seen developers arbitrarly put in break points and debug statements
and then work there way forwards to the point at which the error manifests. Don't do this, precisely becuase your break point or debug statement *is* arbitrary*.
Becuase the framework or library you're using may have poorly understood or poorly documented, unpredicatable
or plain broken behaviour, then place your breakpoints or add your logging there first and only then work your way forwards.

UX:

"Always assume your user is deaf, dumb, blind and stupid." No offence meant *whatsoever*. If you can get your project to be used by someone of this ilk, you've already won.

PHP's "statics"

1. Static methods within a class.

Note: Allows dev's to encapsulate similar methods within a class, but with the "benefit" of easy access by means of global scope.
Reference: http://php.net/manual/en/language.oop5.static.php
Example:

class Foo
{
