The mythical "edit button," which Twitter users have been wanting for so long that it's become a meme, is finally becoming a reality.

Since last year, Twitter has revealed that it has been working on a long-awaited edit feature. Elon Musk, a new Twitter board member and stockholder, polled followers on Monday to see if they wanted an edit button.

Users of Twitter Blue, the platform's paid membership service, will be able to test the much-anticipated feature "in the coming months," Twitter said in a tweet.

In a post on Tuesday, Jay Sullivan, the company's VP of consumer product, stated that editing has been "the most requested Twitter feature for many years." Since last year, the company has been researching how to develop the function "safe manner."

"Without things like time limits, controls, and transparency about what has been edited, Edit could be misused to alter the record of the public conversation," he said. "Protecting the integrity of that public conversation is our top priority when we approach this work."

Musk asked his followers to vote in a poll on whether the platform should enable an edit function on Monday evening, just hours before Twitter announced Musk's appointment to the board.

"The consequences of this poll will be important. Please vote carefully," said Twitter CEO Parag Agrawal in response to Musk's tweet.

Musk created a separate poll on Mar. 25 asking followers if they believed Twitter upheld free-speech ideals, and Agrawal's quote-tweet appeared to be a reference to Musk's earlier tweet. Underneath the survey, Musk had used the same caution.

On Tuesday, Twitter stated, "no, we didn't get the idea from a poll" when it announced the edit feature was in development.

People have been requesting an edit button for so long that it's become a running gag. When a typo in a popular tweet is discovered, the typical reaction is "Tweets, but editable." However, Twitter's former CEO, Jack Dorsey, was previously hesitant to provide such a function.

Dorsey expressed concern during a talk in 2018 that an edit button may allow users to modify the meaning of a tweet after it has been widely shared, and in 2020 he claimed Twitter will "probably never" introduce the feature. Concerns like these have repeatedly arisen in response to calls for an edit button.

After Agrawal became CEO, Twitter's stance on an edit button appears to have shifted.

The edit button will be tested later this year on Twitter Blue, a $3-a-month subscription service that lets you undo tweets and read ad-free articles.
