A better business model would be to charge progressively based on number of followers. This way users pay not for consumption, but for amplification of their messaging.
Something like
0-100 followers : free
100-1,000: $5/mo
1,000-10,000: $20/mo
...
1M+ : $10,000/mo per 1M
The aligns the incentives and value provided. Someone having 1M followers on twitter has a powerful platform for their agenda whatever it may be. This should come at a progressively higher cost to them (not their followers).
