Sharing Tweets via Email

Twitter introduced the ability to email a Tweet directly from twitter.com

You can email a Tweet to anyone, whether they use Twitter or not, right from your Twitter stream or from the details view of any Tweet. Use “More” icon next to the reply, retweet and favorite buttons in order to email a Tweet to anyone you know. You can add your own comment, and Twitter will send an email with your comment and the Tweet together. So easy.
