1. Twitter's new subscription service just launched in the US. The service, Twitter Blue, kicked off in Canada and Australia in June. Now, it's available stateside for $2.99 per month. Here are some of its features:

• An undo button. Notice a typo? Have a bad take? Users can preview and make changes to a tweet before it's public - but they'll only get up to 60 seconds to undo it. While all users can delete a tweet after it posts, Twitter Blue will let you recall it before it sends.
• Ad-free articles. Through a partnership with more than 300 news outlets - including Insider - Twitter Blue users can access articles without seeing ads. A few caveats: this isn't yet available on Android devices, and it won't get you past a website's paywall.
• Bookmark folders. Users can sort their saved tweets into different categories for easier access.
