Suzanne Xie, Twitter’s director of product management, let the world know about one of Twitter’s upcoming downgrades: restrictions on conversation.
More specifically, users will be able to control the conversation around what they tweet. On the compose screen, users will be presented four options: Global, Group, Panel, and Statement. From The Verge article:
Xie says Twitter is adding a new setting for “conversation participants” right on the compose screen. It has four options: “Global, Group, Panel, and Statement.” Global lets anybody reply, Group is for people you follow and mention, Panel is people you specifically mention in the tweet, and Statement simply allows you to post a tweet and receive no replies. (No word on whether Statement also automatically formats your tweet as a classic iPhone Notes app apology, but it should.)
