In a bid to cement itself as the definitive real-time news commentary engine of the modern universe, Twitter has (smartly) decided to add a bit of context to embedded tweets. Increasingly, blogs and news sources are embedding tweets that relate to a story they're composing, but to date, those tweets have largely sat on their own island. Starting today, embedded tweets will include a "Related headlines" section beneath the original tweet, where you'll be able to view the tweet's permalink page as well as lists and links to websites where the tweet was embedded. All in all, it seems like a wise move for the company, but curiously, it's not clear how the shown links are chosen. Something tells us every news organization on the planet will be pleading to be first for inclusion, though.
