One of the new features of the New Twitter is that they have made it easy to embed tweets on your website.
Several solutions already existed though Twitter has now made it easier than ever before.
The company is offering the ability to get the embed code for individual tweets from their own website.
Search API will now always return “real” Twitter user IDs. The with_twitter_user_id parameter is no longer necessary. An era has ended. ^TS

Twitter is also now support oEmbed so if you are already using a compatible web app, you can now start embedding Tweets automatically.
The Embedded Tweet feature allows websites to generate copy and paste-able HTML markup to render a Tweet on any third-party website. This markup presents a Tweet in an attractive (and display guidelines compliant) way, and automatically sets up Web Intents so that viewers of the Tweet may retweet, reply, favorite, and follow easily from the rendered view.
