David Isenberg notes that one's position in a Power Law-based population isn't permanent. Yahoo and Google are permanently popular; they have low Zipf volatility. But my hypothesis is that there's a middle tier of blogs with high Zipf volatility, where a well expressed idea or a funny story or a new factoid can rapidly catapult a blog from #100,000 to #1000, or in rare cases even to #10, in a matter of hours. Some subset of these will stay more popular than they were before, others will drop to that same pre-bubble level. Not unlike Income Mobility.
