If you use the official Twitter iOS app, you may have noticed something missing today: @username handles in replies. I wasn't a fan of the reworked style when it popped up on my Android device recently, and neither were many of the people affected by the change today. The one upside however, was that since @names no longer applied to the character count, some users created a massive "Twitter canoe" mentioning everyone they could. Anyway, it has now reverted back to normal for all users, and in a tweet, the company explained: "an experiment around replies accidentally went out to everyone on iOS briefly."
