Four reviews now exist on Amazon.ca about this book, all of them rating the book at five stars, all of them published between February and August, 2010, and three of them from Vancouver, BC where the author seems to be based. I always wonder what's going on when a book has only a very few reviews, all of them five-star, coming soon after the book came out, with most of the reviews all come from the same city. I've been burned too many times by allowing myself to be guided into a purchase by reading the reviews on Amazon, then buying the book, as I did with this book.
It is always a good idea to check how many used copies are available for sale, and at what price. If the book is heavily discounted, perhaps there is an oversupply and/or buyers are not hanging on to the book.
It is also a good idea to read an excerpt or two from any book that one is going to buy. Here is brief one from page 97 of this book:
"22 Types of Updates You Can Post on Twitter" (I will only list the first several -- in fairness, please buy the book if you really need to see all of these):
1. Where you are physically located a given moment
2. A link to a picture of an event you are attending
3. A question about a business challenge
4. A question about a popular topic in the news
5. Share a link about your most recent blog entry
6. Share a tip on your area of expertise
7. Share a link to a breaking news story
8. Retween someone else's update that your followers would find useful
9. Answer someone else's question ...
OK .. you get the idea .. buy the book if you need to see tips 10-22 about what to tweet on Twitter. Basically, you write something, you have your friends write about it, and you create a buzz.... as seems to have happened with this reference book which, as the title of my review indicates, is a "resource" that "might" be dated and/or too basic for many readers.
