I had this book about 10 years ago.

Nice to look back and see what possibilities were imaginable back
then.

Barbara Jacobs offered a glowing review of the book. Yet although she did not talk about powerful tools like blogs, wikis, podcasting, rss, etc., Jacobs was spot on when she stated that "[t]he power of the 'digital estate,' predicts former publisher and (then) IBM vice president Martin, will be far more overwhelming than its fourth estate counterpart."

4th estate < 5th estate. Indeed.
