After years of discussions and demands from users such as tech billionaire Elon Musk, the short message service Twitter has announced that it will test a so-called edit button for post-editing tweets.

The function should initially only be introduced as a pilot project for subscribers to the payment service Twitter Blue, as the company announced on Thursday.

"Within a short period of time there is the possibility, for example, to correct typos and add missing tags," explained Twitter.

During the test phase, tweets can therefore be edited a few times within 30 minutes of their publication.

Changes should then be made visible with a symbol, a time stamp and a label.

"We really hope that with the availability of the editing function, tweeting will feel easier and less stressful," said Twitter Germany boss Jolanta Baboulidis.

Demands for an edit button have been around for a long time.

In April, Elon Musk - after joining Twitter as an investor - launched a survey on the Edit Button.

The proposal met with great approval among users.

However, the result is not considered representative.

However, there are also concerns about the feature.

One argument against this is the fear that tweets could be modified after they went viral, thereby distorting their core message or misusing them for advertising messages or propaganda, for example.

Twitter pledged to pay close attention during testing to how the feature affects the way people read, write, and engage with tweets.
