1. The deployment is just two clicks.

2. Applications can interact, i.e., your app can use the log app for logging, the profile app for accessing user profiles, etc. So each app does only one thing, but does it well. It can be imagined as a social network, whose logic and content is formed entirely by users.

For instance, can anyone link their app with mine? How do we keep everything consistent?

use('log', '0.1');

...

log.debug('Your log message');

The first line includes the file http://www.akshell.com/apps/log/code/0.1/__init__.js which is an interface of log. Then you can view your logs at http://log.akshell.com/

The admin of log maintains consistency of the interface; so other developers can use it.

Anybody can use your app if he trusts you. If you don't maintain consistency of your utility interface, nobody will use it.

It is not like friending. The friending itself can be implemented as an application.
