The home of the Big Mac has active Twitter presence, averaging 2,000 @replies to followers every week. McDonald's has more than seven million Facebook fans as well.

One recent campaign that was on social media's center stage was the introduction of the McRib, with ordinary users pressed into service as McRib Superfan spokespeople, and a video contest across the U.S. for fans to share their passion for the meaty sandwich. The sandwich launch ultimately boosted the company's presence across all social media, despite a small backlash among fans and followers who thought the McRib didn't taste that good, in real life. The lesson there is: No matter how good a company's social media presence is, it can't fix everything.
