Facebook has 40m active small business pages

"Facebook is announcing some new programs today for small businesses, particularly ones that advertise. At the same time, the company’s also arguing that plenty of businesses find out value on the social network without buying ads.
Specifically, Facebook says the number of active small business Pages keeps growing — it’s up to 40 million, compared to 30 million last June. And only 2 million of them are active advertisers."
