Dan Fost in a LA Times story
Facebook is not just for friends anymore. The free social networking site -- blocked in many workplaces as a potential time-waster -- is increasingly becoming an inexpensive marketing tool for small businesses. . .
Facebook doesn't break out figures for small businesses but says it has 1.4 million business "pages," with an average of 100 fans per page. Facebook Chief Operating Officer Sheryl Sandberg said in a speech in New York last month that every day, 10 million people become fans of pages.
Businesses need to go where their customers are, and increasingly these days, that's on Facebook and other social media sites, analysts say. More than 300 million people have signed up for Facebook, and half of them visit the site every day.
