Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Excellent starting place

I consult to starting, small, and 'stuck' nonprofits. This book is a great starting place for any of those classifications. It is waaay over-written in places - lots and lots of exercises and repetition of ideas. But the concepts are right and solid, and built into a framework that an organization can tackle on their own... without a high paid consultant like me!
