In both the case of tweets and RTs about 500 accounts create half of the total volume in the conversation. Regular daily participation floats around 3,000 users. Then there’s a large body of several thousand accounts dipping a toe in the conversation.
This suggests that however organized or unorganized the movement, the conversation around #GamerGate on Twitter has a central core limited to a few hundred highly active accounts. The total mass of the conversation is in the tens of thousands, though over 80% of those members are involved on less than a daily basis.
