Buried on page B6 of today’s Wall Street Journal is a small story about Facebook beginning to charge marketers for posts that include offers to their fans. The minimum price will be $5. I’ve often wondered if people — consumers — would use Facebook if there was a small monthly fee attached. Say, $5 or $10 per month. My guess is that Facebook would lose at least of its users if that happened.

Today’s questions is this: will the small fee affect marketers’ use of Facebook? I predict yes. And if you forced me to give you a number, I’d bet 30 to 40 percent of all Facebook offers (discounts, coupons, etc.) disappear as a result of the new fees.
