Sure, people want different facets of themselves on different apps/platforms. But those apps/platforms get bought and sold along with the content and the facet of yourself that you put there. Ergo, I disagree that we don't have a problem. It's just in a different form and involves the business models both companies and users have become used to (e.g free, ad-supported, etc). For the moment, there are still no viable systems people could move to so they just have to deal with what they get (or disengage).
