Query: Don't throw away your money

This is truly a terrible book - very thin on usable content. Further, the author, Chris Pirillo, writes like a high school "valley girl." It is a prime example that the Internet allows anyone - despite how dumb they are - to venture, and in this case, publish their opinions. Don't waste you money. And for the author, become a cheerleader!
