Twitter announced a new feature on Monday called "Related Headlines." This feature seeks to match (some) tweets to news articles and other webpages that give them context by tapping another Twitter feature, embedded tweets.
From Twitter's blog:
Starting today, you will see a new 'Related headlines' section on the permalink page of Tweets that have been embedded on websites. It lists and links to websites where the Tweet was embedded, making it easier to discover stories that provide more context.
Please note that the part of that quote that specifies this feature will only be available on the Web at Twitter's site under the permanent URL for the given tweet (see How to Obtain the URL of any Given Tweet for more info). In other words, it will not be seen in Twitter clients, at least for the time being.
The example Twitter used in its announcement was pro basketball player Jason Collins telling the world he is gay. Mr. Collins later tweeted a thanks to his fans for their support, but that tweet doesn't specifically mention what he was thanking them for.
At the time, the context was self-evident to most folks, but over time that becomes less true, and in other cases there may be no self-evident context.
Related Headlines intelligently lists articles that embedded the relevant tweet, as shown in the image below. The company said this feature will give users that added context they might be looking for.
