Thought: There's going to be a need for a very open platform that can do things like this, which will offset many of the worries that have been echoed on this thread today about one or a few corporations having access to everything.

To use an analogy - if messaging apps are the new "browsers", then content accessed through them are the new "websites". What FB is doing is the equivalent of AOL in the 90s.

What then, is the equivalent of a search engine like Google/Yahoo, in that world?
