This site serves as a community feature server. It supports uploading of Features as well as aggregates feeds of other distributed feature servers.
Of course! It's intended that you register and upload your projects/features to this site to share them with others, if you choose not to run your own distributed feature server.
Taken from Development Seed's article:
"At its simplest, a feature server is a website where someone can get features and get updates for those features. It could be a private repository for a network of Drupal sites within an organization, or it could be a public facing site from which anyone can download and add features to their own Drupal website."
Feature Servers are distributed in that you may run your own Feature Server and share your features with others autonomously. A Feature server does not need to be a 'central' hub where everyone goes to upload their features. However, this site acts as one if you so wish to use it.
Feature Servers implement the UpdateXML logic per the Update module in Drupal, allowing users of features to be notified of updates when you make a new release for your Feature.

Features are a method of exporting the mechanics or functionality of your site into 'meta-modules' that can be installed and enabled on any site, immediately providing that functionality to the different site.
Whereas CCK and Views add functionality to a site, Features can (for example) export node types, the CCK fields, various Views and other settings and allow you to turn on that functionality as a 'feature' on another site.
Essentially it is a way of leveraging functionality traditionally stored in the database, and exporting it into code, which can then be kept under version control etc.

Features can be installed on any regular Drupal site provided its dependencies are present.
A great example of a suite of features that work together is seen in the nuts and bolts of the opensource Drupal-based Intranet package, OpenAtrium.
