Twitter followers is an increasing returns game, like income distribution. This means that the average number of followers is a less useful metric than median number of followers, which is likely significantly lower. (Average will be biased upwards by a small number of uber-popular tweeps, like @scobelizer) I'm guessing median number of followers may be closer to 100 or even 75. - Richard W. DeVaul

I agree with Richard and believe it might even be lower than that, particularly if you read the prior HubSpot reports: http://blog.hubspot.com/blog... and http://blog.hubspot.com/blog... Those 1MM follower races seriously bork average. - AJ Kohn

I wonder how many of those followers are shared. In essence, 10 users may follow the same 10 followers, so the messages from the common followers are effectively diluted by being posted to a common audience instead of a more diverse exposure to unique followers, so average of 116 unique users instead of 126. I may be off a bit, but I see it happen with my coworkers- we all follow each other, so I may see the same message 10 or 15 times. Some are RT while others share the same info but in their own words. - Dan Douglass

those Twitter numbers can be misinterpreted - polou/indigo_bow
