What is a Repost?
A post that you share publicly with your followers is known as a Repost. This is a great way to pass along news and interesting discoveries on X. You have the option to add your own comments and/or media before Reposting. When using X's Repost icon, your Repost or Quote post will reference the post you are sharing. When someone replies to your Quote post, the author of the original post will not be automatically added to the conversation. If you want to include the author of the original post, you will need to mention their username.
In addition to sharing other’s posts on X, with your own post you can Repost or Quote post. This function is particularly useful when you want to re-post one of your older posts because it is relevant again, or Repost your replies to other people when you want to make sure all of your followers see it.
Note: The original post in your Quote post does not count towards the character limit. Undoing a Quote post will remove it from other timelines, however it may still appear on mobile devices displaying cached timelines or in cross-postings to third-party sites.
