Ever made a typo on Facebook? The social network, that caters to 901 million users worldwide, has started to introduce a feature where users can edit their comments on posts and view the edit history, which is something that should be arriving for most users over the coming days.

Up until this point, there was a very limited window to edit a comment. Just a few seconds after posting, if you pressed the X to delete the comment, you had the temporary option to edit the comment for any reason.

Facebook is well aware that typos happen, but now this option becomes a permanent fixture without a time limit. Users can go back and edit any comments that were made on posts on the social network, whether they are from today or last month. When you hover over the top-right corner of your comment, you will now see an option called "Edit or Delete."

Clicking "Edit" will allow you to make changes to the comment, add or delete words and so on. It appears more useful than the temporary editing capabilities because you can now go back through your timeline and edit any comments you made. It is also more useful than deleting a comment entirely and then reposting it, which would otherwise prompt a notification for those involved in the thread.

That's not all.

Facebook has introduced editing history for comments now, which means that once you make an edit, the time stamp for the comment will change and will show "edited" next to it. It is still unclear whether comment editing will be accessible on Facebook's mobile comments plug-in either, which is used by many publishers.

Whether users find this feature useful or totally unnecessary is uncertain. Facebook's changes always leave room for discussion, whether postiive or negative, but one thing is for sure, Facebook seems to be in a never-ending face-lift, whether big or small.
