I hate the idea of cliques (jocks, nerds, etc.) just as much as I hate the idea of baseless notions that extroverts are the slime balls while introverts are the silent heroes. If people hailed the qualities of introverts, then they would be in the position of extroverts, and since introverts presumably dislike being in such situations, they would cease honing the skills like "independence, focus, persistence..." they are admired for.
If the introverts are truly "building the next Facebook/LinkedIn," then their success is derived from the extroverts using it.
It might not be a pretty world, but at least it's balanced (to a decent degree).
