-Node's goal is to provide an easy way to build scalable network
-programs. In the above example, the two second delay does not prevent
-the server from handling new requests. Node tells the operating system
-(through epoll, kqueue, /dev/poll, or select) that it should be
-notified when the 2 seconds are up or if a new connection is made --
-then it goes to sleep. If someone new connects, then it executes the
-callback, if the timeout expires, it executes the inner callback. Each
-connection is only a small heap allocation.
+Node.js is a platform built on Chrome's JavaScript runtime for easily
+building fast, scalable network applications. Node.js uses an
+event-driven, non-blocking I/O model that makes it lightweight and
+efficient, perfect for data-intensive real-time applications that run
+across distributed devices.
