New users may not be aware but established twitter users who follow large numbers of tweeters usually hit a wall when they attempt to add follow number 2001.
So, how do you get past the twitter follower limit of 2,000? Well the only way to do it is to grow your own follower list.
You don’t however have to have 2,000 followers; the magic number is in fact 1,819. Twitter lets you follow the number of followers that you have plus 10%. When you hit the figure of 1819 you are allowed to follow that number plus a further 182. Your follower limit is now 2001 and you have broken through the barrier, just.
For every ten new followers you gain you can follow eleven new tweeters, and so on. Using that formula Ashton Kutcher would be allowed to follow over 5 million users, slightly more than the 320 currently on his radar. So now you know.
