Please use a larger font
Format: Hardcover
Over 60 and sometimes have a difficult time with too small print? My advise .. either read it on an ebook or skip this one.
I read the first chapter despite the small font size that made it a little too difficult to read. While I found it informative and well worth reading I'm probably not going to read anymore and return it to the library. Mass market paperback books with small print I can understand. Hardback non-fiction books (which are generally read by an older crowd I suspect) make no sense to me.
5 stars for the content I read. 1 star (generously) for the font size.

Great review and analysis of a law that underpins the Internet
Format: Kindle
This book provides a detailed history of how section 230 if the Communications Decency Act came to be, its importance and its problems as the industry of the Internet matures. While it is ultimately a defense of that law, it is an eyes wide open look at it as well. It is not a prophet's telling of what to do, but instead an informative read that gives the reader an ability to assess what might be done to address the issues 230 raises.

Dealing with complexity
Format: Kindle
Section 230 is a simple effort to govern what must be the innovation of our time. This account is a great effort to explain the accomplishments and challenges that simple can allow.
