This is the best resource I have found in the library concerning teh use of blogs in American democracy. It is a short read coming in at about 150 pages and gives tons of information about bloggers and their actual participation in politics. Like most political books about stratifying an electorate, it has tons of data. Great resource.
This book is an older version of Davis' later Politics Online. Unlike his later endeavor, Web is a theory based book. It feels as if this book gives Davis' theory for how the internet should work with politics and Politics Online is his research into trying to prove his hypotheses. Still a good earlier work about the potential power of the internet in teh electoral process and delibrative democracy.
