The number of people actively using Twitter by tweeting or creating new accounts peaked in August 2014 and is now in decline, a source with access to Twitter's user data tells Business Insider.
According to Twitter's official disclosure of "monthly active users" (MAUs), the platform's audience hit a high of 288 million in Q4 2014. But MAUs are defined as any user who logs in to Twitter, even if they do not do anything. MAUs thus count a lot of people who use Twitter passively, for instance through mobile phone lockscreen apps that ping Twitter automatically for updates.
Twitter does not break out the number of people who tweet or create an account within a given month. That number — which we're referring to as "people actively using Twitter" for the purposes of this article — is interesting because it describes the users who aren't just logged in automatically because they failed to log out from the month before. Rather, it describes users who are actively, intentionally using the system — Twitter's core audience, in other words.

The company recently moved again to restrict data that gets seen by partner software and app development companies. It terminated agreements with third parties for reselling so-called "firehose data" earlier this month, according to TechCrunch.
Last year, Twitter cracked down on other companies publishing independent user statistics based on Twitter's own data, kicking several of them off the company's API, which is used by developers to make apps and suck data out of Twitter.
The data from our source has flaws: It is not drawn from the full dataset which Twitter uses to compose the MAU counts it discloses to the SEC and investors. And it is composed from a series of sample counts of monthly users, on irregular dates rather than at standard periods.
But it might worry investors ahead of Twitter's Q1 2015 earnings call because it shows another way in which -- For more information read the original article here.
