Twitter considers a "clarification" feature

How it would work: Dorsey was vague on details, but "clarification" seems to be a way to go back and add context to a tweet — similar to the “quote tweet” function, but not quite. Added context would follow the old tweet around, and users could clarify any of their old tweets.

Between the lines: Dorsey seems to be thinking of the countless situations when someone in the public eye has had to explain or apologize for something they’ve tweeted in the past.

• “There’s a lot of value in seeing the history and seeing how people evolve,” he said.
• But obviously, this could also apply to a tweet from minutes ago that was poorly phrased and filled with confusing typos.

Yes, but: The company has considered and even experimented with a number of features and changes over the years that have never materialized.
