Musk frequently uses the platform to publicize his other ventures (including his companies Tesla and SpaceX, as well as pet projects like his flamethrower), but also to share his favorite memes, his thoughts on current events and his musings about life in general.

Seize the memes of production!

Musk’s recent investment has been connected by some commentators to his posts last week about the social media platform, which included a poll to his followers asking whether they thought Twitter did enough to promote free speech.

Given that Twitter serves as the de facto public town square, failing to adhere to free speech principles fundamentally undermines democracy.

What should be done? https://t.co/aPS9ycji37

Free speech is essential to a functioning democracy.

Do you believe Twitter rigorously adheres to this principle?

Many users speculated what Musk might do now that he has acquired a substantial share of Twitter, and how he might change the way the platform functions. Some celebrated the possibility of Musk changing the way Twitter does content moderation and polices speech on the platform.

Others criticized the self-described “bizniz magnet” for his financial adventurism and anti-union activity at the helm of Tesla, expressing concern about the future of Twitter.

Elon Musk has $3bn to buy 9.2% of Twitter but he doesn't have the capital to allow his workers to unionize without busting?

A consistent motif in the memery that emerged in response to Musk’s purchase this morning was what the vibe might be in Twitter’s boardroom when the newest shareholder enters.

Many online commentators also joked and theorized about what might now be possible on the platform, given the change in ownership.

At the moment, Twitter’s biggest shareholders are so-called “institutional investors” — that is, mutual funds or banks that buy shares in companies for others. This means that a lot of Twitter stock is held in retirement accounts or in mutual funds where it is packaged and then sold along with other stocks. Some Twitter stock is owned by employees and founders of the company (Jack Dorsey owns about 2 percent of Twitter). Given how much capital Musk has, it's plausible for him to buy out Twitter entirely. His actions made the stock price jump about 20 percent on Friday. But so far, there are no indications of what his plans might be.

As of the writing of this post, all that Musk has said publicly is this:

Oh hi lol
