Twitter has announced that it is testing  “Circle”, which is a spin on the Instagram “Close Friends” feature. The feature was teased as one of many potential product updates in July, and last month, it cropped up live on the site due to a bug. Now, a small number of users can be able to post to their 150 closest friends as the feature enters a live testing phase.

According to Twitter, the feature is in its early stages, as such only some users have access. Even if you don’t make a Twitter Circle yourself , you can see tweets from users who do have the feature, as long as you’re in their Circle. When you build your Circle, Twitter will recommend that you add mutuals that you interact with often (odds are, those people might be your close friends). You can add people who aren’t following you, but they probably won’t see your tweet because they aren’t following you. When you reply to a tweet that someone sent out to their Circle, other members of the Circle can see your response and interact with it (unless if you’re on private).

Good thing is that when you add or remove people from your Twitter Circle, they won’t know, so no catching feelings. However, you only get one Circle, so choose those whom you put there wisely.

To tweet to your Circle, click the oval above the text box when you’re writing a tweet, then change the audience from “Everyone” to “Twitter Circle.”
