Whether you use Twitter to keep up with friends, market your brand or complain about another brand’s lousy service, the point is: You’re on it. And so are more than105 million other people, according to the Huffington Post. The good news is that brands are actually starting to get this whole “social media thing.” They’re finally allowing employees (if begrudgingly) to tweet and hang out on Facebook during office hours. It’s not that the boss has finally decided to introduce leisure time at work, of course. The hope is that employees plugged into social media outlets will lend the brand’s page or profile a real-world feel, a sense of coolness.
