What if you knew what you were missing on social media?

Social media can feel like a giant newsstand, with more choices than any newsstand ever. It contains news not only from journalism outlets, but also from your grandma, your friends, celebrities and people in countries you have never visited. It is a bountiful feast.

But so often you don’t get to pick from the buffet. On most social media platforms, algorithms use your behavior to narrow in on the posts you are shown. If you send a celebrity’s post to a friend but breeze past your grandma’s, it may display more posts like the celebrity’s in your feed. Even when you choose which accounts to follow, the algorithm still decides which posts to show you and which to bury.

There are a lot of problems with this model. There is the possibility of being trapped in filter bubbles, where we see only news that confirms our pre-existing beliefs. There are rabbit holes, where algorithms can push people towards more extreme content. And there are engagement-driven algorithms that often reward content that is outrageous or horrifying.

Yet not one of those problems is as damaging as the problem of who controls the algorithms. Never has the power to control public discourse been so completely in the hands of a few profit-seeking corporations with no requirements to serve the public good.

Elon Musk’s takeover of Twitter, which he renamed X, has shown what can happen when an individual pushes a political agenda by controlling a social media company.

Since Musk bought the platform, he has repeatedly declared that he wants to defeat the “woke mind virus” — which he has struggled to define, but that largely seems to mean Democratic and progressive policies. He has reinstated accounts that were banned because of the white supremacist and antisemitic views they espoused. He has banned journalists and activists. He has promoted far-right figures such as Tucker Carlson and Andrew Tate, who were kicked off other platforms. He has changed the rules so that users can pay to have some posts boosted by the algorithm, and has purportedly changed the algorithm to boost his own posts. The result, as Charlie Warzel said in The Atlantic, is that the platform is now a “far-right social network” that “advances the interests, prejudices and conspiracy theories of the right wing of American politics.”

The Twitter takeover has been a public reckoning with algorithmic control, but any tech company could do something similar. To prevent those who would hijack algorithms for power, we need a pro-choice movement for algorithms. We, the users, should be able to decide what we read at the newsstand.

In my ideal world, I would like to be able to choose my feed from a list of providers. I would love to have a feed put together by librarians, who are already expert at curating information, or from my favourite news outlet. And I’d like to be able to compare what a feed curated by the American Civil Liberties Union looks like compared with one curated by the Heritage Foundation. Or maybe I just want to use my friend Susie’s curation, because she has great taste.

There is a growing worldwide movement to provide us with some algorithmic choice — from a Belgrade group demanding that recommender algorithms should be a “public good” to European regulators who are demanding that platforms give users at least one algorithm option that is not based on tracking user behaviour.

One of the first places to start making this vision a reality is a social network called Bluesky, which recently opened up its data to allow developers to build custom algorithms. The company, which is financially supported by the Twitter founder Jack Dorsey, said that 20 percent of its 265,000 users are using custom feeds.

On my Bluesky feed, I often toggle between feeds called Tech News, Cute Animal Pics, PositiviFeed and my favourite, Home+, which includes “interesting content from your extended social circles.” Some of them were built by Bluesky developers, and others were created by outside developers. All I have to do is go to My Feeds and select a feed from a wide menu of choices including from MLB+, a feed about baseball, to #Disability, one that picks up keywords related to disability or UA fundraising, a feed of Ukrainian fund-raising posts.

Choosing from this wide selection of feeds frees me from having to decide whom to follow. Switching social networks is less exhausting — I don’t have to rebuild my Twitter network. Instead, I can just dip my toes into already curated feeds that introduce me to new people and topics.

“We believe that users should have a say in how their attention is directed, and developers should be free to experiment with new ways of presenting information,” Bluesky’s chief executive, Jay Graber, told me in an email message.
