Obviously, but that's not what I'm getting at. Due to present technical limitations, "influencers" have to sharecrop for Google/Facebook/Twitter/etc. Bandwidth/storage/software improvements will allow successful "influencers" to flee the plantation.
Not until we solve the discovery and filtering part as well, at the very least. I'd say that is the largest value these platforms bring to the table, hand in hand with their existing network too of course.
