As investors in not only Facebook but also other Web companies such as Yelp and Pandora realize, it's hard making money on Web-based ads. The fact is, users have been trained to ignore advertising, and rates continue plummeting as the inventory for ads far exceeds the amount of advertisers willing to start campaigns with higher advertising dollars per impression. Online advertising is a rough industry, with only search leader Google seeming to have "figured it out."

Yet a small piece of news most investors ignored on Friday might point the way to future Facebook success. The company is running a test to allow targeting based on user IDs, emails, and phone numbers. That's important, because it helps satisfy a difficulty with display advertising: relevancy. With a new program, a variety of advertisers with large email lists could target users who they know have an interest in their product. 

To be sure, this doesn't fix Facebook's problems turning millions of eyeballs into ad dollars, but it does begin to show how they're using their massive data hoard to be something more than a basic display-advertising company.
