Micro-blogging site Twitter is considering the possibility of adding support for editing tweets, but the original version of the tweet would still be viewable.

"Maybe we introduce a 5-30 seconds delay in the sending of tweet and within that window, you can edit because the issue with going longer than that is it takes that real-time nature of the conversational flow out of it," 9To5Mac quoted Twitter chief executive officer (CEO) Jack Dorsey as saying in a podcast interview on Saturday.

On why the micro-blogging site lacks the feature, Dorsey said the platform was built on the SMS format of text messaging.

"Once you send a text, you can't take it back. When you send a tweet, it goes to the world instantaneously. You can't take it back."

Dorsey first addressed the possibility of adding an edit feature for tweets in December 2016, based on the Twitteraties' suggestions.
