Twitter has launched a $99/month tool that lets users constantly promote their content. Known as "Promote Mode," the subscription is first rolling out in beta form in the United States and UK. Users paying for promotion will see their tweets and profile show up in other users' feeds.
Promote Mode, an always-on form of advertisement, initially appeared as an invite-only service during the summer. Now it's rolling out to everyone as a public beta.
Users can easily see stats related to their subscription, letting them know how many followers they've gained, how many visits they've received, and how many views they've had.
