Even before Barack Obama was sworn in as the nation's 44th President, he was a big fan ofsocial media. On Election Day in 2008, for instance, Obama had380 percent more Facebookfans than his rival John McCain (R., Ariz.). So it's little wonder why today's White House has an entire staff dedicated to operating a YouTube channel, filtering photos onInstagram, crowdsourcing petitions onWe The People, hosting Q&As through Twitter and even hang outs with voters on Google+.

I spoke toMacon Phillips, the White House's director of New Media, to discuss why the current administration is all a buzz over social media. Here's how his team is using social tools to engage with the public in the digital age:

How do you engage with the public differently on Twitter vs. Facebook?
Just after the president gave his speech on the nation's state of the union, we held a series of Twitter Q&A sessions with more than 30 senior administration officials. We were able to do that because Twitter is a much more conversational medium. Facebook, rather, is a better place for sharing rich content. We see that people regularly share our "photos of the day" and videos on Facebook.

What is the strategy behind your use of YouTube?
We've put together a series called "West Wing Week," which offers an update on the President's weekly activities such as when he travels and meets with foreign dignitaries, business groups, veterans or staffers. In addition, we have another video series called "The White House White Board," where we look in depth at an issue like tax policy.

What is the White House's most popular content to socialize?
We worked with the White House Photography Office early on to set up our President on Flickr. As a result, people can go to Whitehouse.gov and sign up to get a photo of the day, which will hit their inboxes every morning.

总统最近的头条新闻后,他走了ogle+ hangout attracted thousands of questions. What did you learn from the experience?
The hangout session is something we are planning to do more of, but it doesn't always have to involve the President to be meaningful. In fact, we helda hang outright after that forStartup Americawith Gene Sperling, the director of the National Economic Council; Steve Case, the chairman of Startup America and Aneesh Chopra, the White House's chief technology officer. They were able to have a face-to-face conversation with business owners around the country about what they're doing on the frontlines and how the Obama administration can be as responsive as possible to their needs.

What are the top social strategies you've learned that entrepreneurs can also use to grow their businesses and following?
Go out early and often.When it comes to social media, we do have goals in mind. But we don't sit around for weeks cobbling together an iron-clad plan before we act. We go out there, listen, get feedback, iterate on that and try to improve. It's as important to listen as it is to speak.

Timing is vital.One the most significant campaigns we ran on Twitter was the#40dollarshashtag, which helped crystallize how people viewed extending the payroll-tax cut. It's about being aware of what's going on and understanding that in the age of social media, you're just a participant. It's not something that you can control.
