Just run the numbers. For one, there are approximately 3M people with 1k followers or more. If they charged an average of $5/month, many (most) would simply not pay. A significant number of those people are international. Many of them did not even try to get followers. Even if all of them paid, $200m/year does not come close to justifying Twitter's valuation. Trust me on this, Twitter doesn't want to mess with the head of the distribution. The backlash would be terrible, and it would destabilize their ecosystem.
