For 24 of the most used languages in the world we are keeping track of the most popular active Twitter accounts. These are not necessarily the accounts with the most followers on Twitter, because we only track the following of active Twitter accounts, so inactive followers are not counted. We basically disregard all inactive Twitter accounts. A Twitter account is considered active when it posted at least 1 tweet in the last 60 days at the moment the overview was created. The tweet can also be a reply, or a retweet.
Each account in the ranking receives a score that is related to the most popular account in that language, which gets a score of 10. At this moment you can see the top-1000 by language.
