Twitter is launching an edit button, after years of internal and external debate over whether this feature was a good idea for a product known for making posts go viral.

The editing feature will soon be available to users who pay $4.99 per month for a Twitter Blue subscription. Edit Tweet will allow users to make changes to their tweets up to 30 minutes after they were originally posted. Tweets that are edited will have a label, and others on Twitter will be able to click on it to see previous versions of the post.
