The day after Thanksgiving, almost one month after Elon Musk turned the proprietor of Twitter, he returned to one in every of his passion horses. “I’m simply preventing without spending a dime speech in America,” he wrote in a tweet.

One in all 28 that he posted that day — starting simply after midnight, following messages about how tasty his vacation meal was — the free speech tweet was in response to 2 followers who had been aggrieved about how Mr. Musk was being handled since buying the social community in late October. The put up was preferred greater than 46,000 occasions.

Mr. Musk has typically stated that Twitter must be extra open and full of a better variety of voices and factors of view. However Mr. Musk’s Twitter feed is commonly an echo chamber. He often sees, likes and replies to messages which might be about him or are posted from accounts that always act as his cheerleaders, in accordance with a New York Occasions evaluate of his exercise on the platform.

With a view to assess how the social community might evolve underneath Mr. Musk’s watch, The Occasions reviewed almost 20,000 of his tweets, analyzing posts from current years and pictures he printed over the previous decade, in addition to the comparatively small variety of customers that he follows.

What Mr. Musk says on Twitter has an enormous attain, now greater than ever: His viewers is among the largest, with almost 128 million accounts following him. It’s the place he solicits recommendation, conducts polls, condemns censorship and publicizes sweeping coverage adjustments on the platform. As an influence consumer who now controls the corporate — he just lately known as himself the “chief twit” — Mr. Musk has vowed to remake the social community in his imaginative and prescient.

Of the 178 accounts that Mr. Musk adopted as of Tuesday, most had been associated to his companies, or have expressed admiration of his enterprise model, the Occasions evaluate discovered. The listing is closely male: Solely two dozen that aren’t institutional or organizational accounts belong to ladies. He’s associated to 2 of them — his mom, Maye, and sister, Tosca — and was married to a 3rd.

Amid discussions of Twitter insurance policies, web satellites from SpaceX and Tesla software program updates, his posts have a freewheeling high quality to them. He traffics in juvenile humor and vulgar jokes (photos of tape dispensers laid in sexual positions), scientific marvels (the Massive Hadron Collider), in style topics on far-right websites (Pepe the Frog) and critiques of divisive cultural points (“I’m not brainwashed!!”).

Mr. Musk’s posting model is conversational, and often satirical. He messages with former Democratic cupboard officers, criticizes information organizations and trades barbs with enterprise capitalists.

“The buying of Twitter was an influence transfer, politically,” stated Joan Donovan, the analysis director of the Shorenstein Middle on Media, Politics and Public Coverage at Harvard. “He is among the richest man on the earth shopping for a social media firm in a transfer that’s expressly about politics and affect on tradition and on media.”

Typically, his updates are restricted to simply memes — joking pictures or movies which might be copied and extensively shared. Many have origins on fringe websites or cryptocurrency message boards which might be in style along with his followers. Some are about him. Some seem like authentic.

Mr. Musk didn’t reply to a request for remark about his exercise. At Twitter, as with a lot of his different firms, Mr. Musk has no conventional press workforce. As an alternative, he tweets.

Since he created his account in June 2009, Mr. Musk has posted greater than 21,000 occasions. In recent times, that has meant posting all hours of the day, most days of the week.

Mr. Musk has “made himself unignorable by changing into king of Twitter,” Ms. Donovan added.

Over a 48-hour interval in November, a second when he touted report exercise on the social community underneath his management, Mr. Musk posted 60 occasions. His posts included commentary on the collapse of a cryptocurrency and combative responses to critiques about his office insurance policies. In a single occasion, he issued a decree about parody accounts after customers modified their profile names to mimic him.

Lots of his missives rapidly turned in style amongst his followers.

It’s unclear precisely what Mr. Musk sees in his feed. The precise sequence relies on whether or not he has chosen to obtain algorithmic suggestions or simply tweets from accounts he follows. (He has beforehand tweeted that individuals are being “manipulated by the algorithm.”)

His exercise more and more consists of replying to customers who’ve talked about him. When he responds to accounts that he doesn’t comply with, he continuously chooses those who have complimented or praised him: In dozens of situations over the previous six months, in accordance with the Occasions evaluation, he has replied to tweets from customers whose account descriptions point out that they help or spend money on firms owned by Mr. Musk, or that they’re followers of his management.

There are occasions when he second guesses what he broadcasts.

Over the previous two years, he has deleted a whole lot of tweets inside hours of posting them. In accordance with the PolitiTweet web site, which archives all of Mr. Musk’s tweets, he has additionally deleted dozens of tweets within the months since he acquired Twitter.

On Nov. 14, for instance, Mr. Musk tweeted that he could be “working and sleeping” at Twitter’s headquarters in San Francisco till the positioning was mounted.

An internet site monitoring Mr. Musk’s personal jet motion recommended that he traveled away from San Francisco round that point. He deleted the tweet 18 hours after first posting it.

However for an individual with as massive of a follower base as Mr. Musk has, deleting tweets might do little to vary how extensively seen or influential these posts grow to be when they’re first printed.

“Tens of millions of individuals see his tweets, not many will discover when they’re deleted,” Ms. Donovan stated.

Many tweets which have landed Mr. Musk in scorching water stay on-line.

In 2018, just a few weeks after Mr. Musk had smoked marijuana throughout an on-camera interview for Joe Rogan’s podcast, Mr. Musk tweeted that he had the funding to take Tesla personal at $420 a share.

Consultants started to query whether or not his complete feed was being produced in jest, and identified the repeated marijuana references in his tweets (together with his proposed funding value).

That incident led to an inquiry from the S.E.C., and later a settlement that included monitoring of what Mr. Musk might put up about Tesla on Twitter. Shareholders are actually additionally looking for billions of {dollars} in damages in a lawsuit after Mr. Musk’s takeover proposal by no means materialized.

Final week, Mr. Musk joined an investor name as Tesla reported its current quarterly earnings, which confirmed a decent soar in income regardless of a rising listing of issues plaguing the corporate. The automaker’s blended efficiency final 12 months had led many to query whether or not Mr. Musk’s focus and a focus on Twitter had meant that he was neglecting his duties at Tesla.

Mr. Musk deflected that criticism on the earnings name, suggesting that his 127 million followers on Twitter was an indication of his recognition.

“I may not be in style with some individuals,” he stated, “however for the overwhelming majority of individuals, my follower depend speaks for itself.”
