"Chief Operating Officer Sheryl Sandberg said recently at the AllThingsD D11 conference that Facebook wants ads to be as useful as other content, but she admitted, “We’re pretty far from that goal.”

Web advertising is all useless.
Maybe for Facebook, but Google is thriving. Search engine ads work fine because people are asking for the ads. Facebook just shoves ads in your Face.
