Google adds email, a *new* newsgroups, searching through book texts, the purchases you mentioned, the toolbar, etc. etc.
Isn't it vividly clear: They are trying to OWN the Internet!
First, they index the entire network and then integrate this database with their shopping engine, email, newsgroups, blogs and eventually they have their fingers in all the information on the 'net. (That is, they have it indexed and/or own it)
Then they start putting a price on it.
World domination soon follows.
