Twitter’s answer to Instagram’s Close Friends is now rolling out widely

When logging into Twitter, whether entering from a browser or from your smartphone, some users have begun seeing a pop-up to tweet to your Circle. Entering the “Compose tweet” panel and tapping on the audience button above (which is set to “Everyone” by default but also lets you tweet to Communities if you’re in any) will show you a new “Twitter Circle” option. You can add, and remove, people from your Circle by tapping the “Edit” button — people won’t be notified if they’re added or removed from someone’s Circle. Likewise, if you see a tweet posted to someone’s Circle, you’ll also see a green notice telling you that only people in their circle can see that post.
