Of course, the simple solution is to charge users a small annual fee for advanced features if not even for basic account maintenance. Your FB profile would become read-only if you don't pay an annual fee.
It's always so intriguing to me that people cling so hard to the ad-supported models even though it's shown that they simply don't work except in anomalous cases, not even for Facebook, which surely receives humongous portions of all net users' attention. It's not a good starting strategy for anyone, and it appears that it's not a good long-term strategy even for the lottery winners that have actually "made money" from it heretofore.
