Shorten the path to a valuable experience.

What's valuable?

Objectively this is a sufficiently fast, smooth, and beautiful GUI without bugs. 

Subjectively; people use a social app for the people, content, interaction and connection. This value is found by tailored discovery of aforementioned, which can be achieved by an open and permissionless marketplace where suggestion- and moderation algorithms race to become as good as possible at delivering value.

More generally:
Delivering a better, cheaper, quicker, or unique experience compared to existing alternatives. Where the benefit of switching to the new solution is obviously greater than the cost/effort of switching and inertia to the current solution.
