Fun read about Twitter! I don't have an account, but I have "tried" to follow certain hash tags in the past. After reading this book, I have an whole list of web sites offer helpful ways to do that way more easily! You can even find local or trending topics, etc... I am almost afraid to sign up for an account now that I know a lot more about it! lol!
If you don't "get" Twitter, this is the book for you! Don't blame me if you spend hours on it though using all the tips from the book! It's the author's fault!
