Well… You obviously get an idea if you take a look on your number of followers. But when a tweet is retweeted by someone, this “someones’s followers” are also receiving – and probably reading – your tweet as well.

This is what I call 2^nd level Followers: the number of users who are receiving your tweets, but who are not following you directly. And there can be many!

Here is an example, with this @jbruin conversation read by 350,000+ users, where she has “only” 9,500 followers.

Because this number is different for every tweet you make, it is displayed on every Twitoaster conversations pages. A good metric for measuring how viral a tweet can be!

I also included an average count of these second-level followers on your profile pages, next to the regular followers number.

Let me know what you think about it!
