Twitter announced today that it will soon roll out a design tweak that will hide @username replies on verified accounts.
Twitter's current design shows all tweets the user has created, so relevant updates can often get lost in a sea of replies on the account's profile page. This will change with the latest update -- all tweets that begin with @username will be hidden in verified accounts. However, you will still be able to easily access these tweets by selecting "All" above the timeline on the profile page.
According to Twitter's Blog, the new, simplified profile will make it "easier to understand what kind of content the user shares on Twitter." This feature will be super helpful when determining whether or not you want to follow the account, and you can quickly see what the company/person is saying, even if they frequently reply to their followers.
Note that the update will only hide @username replies that appear at the beginning of the tweet. Those @username replies that are inserted at the end of the tweet (or after a period) will still appear on the profile page.
Expect to see this new feature on your favorite verified accounts over the next couple of weeks.
