What Yahoo could be: A social graph that's not a walled garden. Want to add Facebook stuff to your page? Sign the Facebook ToS, lube up, and get ready to get shafted. Want Google+ interaction? Same deal. Facebook (and to a lessor extent, G+) don't want you to run apps that involve them. They want you to create content for users to "like". Yahoo could create a great identity system - multiple identities (so you don't need to use your real name for everything), notifications (replacing email for web apps), payments, micropayments, advertising, the works. Want to make a web app? Check out (the fictional) Yahoo.js, and the (fictional) native client for your server (or just make it all run on JSON as a fallback). It could work like that. They just need to ask a bunch of people making new web apps what the pain points are, solve them, then use that to push people to a Yahoo Notifications page, and from there to Yahoo's other properties.
