Twitter users have had the ability to quote another tweet for a while that gives you the option to add some of your own comment to a tweet. When you only have 140 characters to work with, having to quote a tweet in your tweet leaves little room for your thoughts. Twitter is now testing a new feature called retweet with comment.
The new feature allows the user to retweet the original tweet and add their own comments without using any of their 140 characters for the quote. Random twitter users are now seeing the retweet with comment feature right now after the feature was tested with some twitter workers internally.
While this new feature sounds like a really good idea, there is no guarantee that it will be permanently implemented into the twitter app and website.
