Micro-blogging site Twitter is rolling out a way for people to sign up to 'Revue newsletters' directly from tweets. According to Engadget, when someone shares their Revue newsletter, the tweet will include a subscribe button.

If someone clicks a link to a specific newsletter issue, they will see an option to subscribe when they return to their Twitter feed. The feature is live on the web now, and it is coming to iOS and Android soon.
