So, how many such “active” Twitter users are there?
Less than 21 million.
Our source’s API data shows that there are 21 million accounts on Twitter following 32 or more accounts.
Oof.
At this rate, Instagram could have more active users than Twitter in a few years. This also goes back to what I whine about all the time; the fact that the original SUL had skewed the perceived activity of followers on Twitter. Many people have over a million followers on Twitter but that number has been stagnant since the original SUL went away. In fact, take a look at the next time somebody with over a million followers takes a picture. The views for that photo give a great indication at how many of those followers are still active.
