Was able to connect accounts, use hashtags, add widgets, set up desktop clients, understand the business uses of Twitter. Most basic questions answered reasonably clearly. I have to admit to a prejudice against "For Dummies" books for years. It is only when I absolutely cannot find another alternative will I pick one up. However, some of them, perhaps even many of them, are done well. They are clearly written and answer the questions I need answered. Why the prejudice? Can you guess? Vanity, ah vanity.
