If we don't know where we've been, how will we know where we're going? It's somehow reassuring to learn that a technology which seems to be so new and to change at lightning speed actually has a history spanning several decades. This book is intelligently written; it's not for the reader who is looking merely for fluff and sound bites. I've recommend it to many friends in a variety of fields since internet technology, and the decisions that have been made about it, affect us all in one way or another.
