Twitter continues to tweak their service to give you more space in your replies on the service. Starting today, the company is rolling out an update to users that eliminates the username of those to whom you are replying to from your 140 character limit. This means you will have those characters to formulate your reply and, hopefully, not have to do so in multiple Tweets.
How this works is pretty straightforward. When you reply to a Tweet, the @username part is removed from the tweet but you are shown who you are replying to at the top of the page on your Android phone. While this isn’t a big deal for individuals you are replying to, for large groups, it is a big space saver.
