Jack Dorsey: Twitter is considering 'clarification' feature

Twitter doesn't have an edit button, but it could one day have something close. Sort of.
CEO Jack Dorsey said the company is thinking about a "clarification" feature that would allow users to include additional context for old tweets. Speaking Thursday at Goldman Sachs' Internet and Technology Conference in San Francisco, Dorsey said the company is considering such a feature as a potential way to help people feel more comfortable about what they share on Twitter.
