Facebook has allowed users a similar feature since ages in the 'Share' functionality. When users on Facebook share a status update from someone, it is a cross between a retweet and an embed in Twitter terms.
Twitter now seems to have gained some lost ground.
When to embed a tweet?
I can think of many reasons why such a feature would be useful. Embedded Tweets actually look a bit like quotations with indentation, while still retaining the integrity of the tweet format. Embedding tweets also is a better approach if your objective is to share without for the sake of itself (since an embed can't be tracked like a retweet).
Retweets also leave you with a limited character space to add your own views. Often, the original tweet has already filled up the 160 character limit, leaving behind nothing. An embed, however, should give you plenty of room to add your own opinion.
Here's what an embedded tweet looks like.
Embedding a tweet within a tweet is very easy. You just type out your tweet, include a link to the tweet you want to embed, and then publish it. The tweet you link to gets automatically embedded into your tweet.
How to get a link to a tweet? This unfortunately requires some extra clicks. Click on the username of the tweet's author, and go to their profile. Find the tweet you're looking for, and click on it. If you arrive on a page that has nothing but a single Tweet on it, you can go ahead and copy the URL of that page - this is the public URL for that Tweet. You can also arrive at this page by clicking on the timestamp on a Tweet. Here's what such a page would look like.
The links aren't immediately clickable, so if someone’s embedded tweet looks interesting you have to click on it to expand it. Twitter’s desktop app, TweetDeck, doesn’t appear to be supporting this feature yet. As of now it’s only available on the iOS and Android apps, and Twitter.com.
Another nice part about this feature is that when you embed someone’s tweet, that person receives a notification. It’s also fun to note that if you embed a tweet with an embedded tweet into another new tweet, they all link together in a chain of tweets.
