After Yahoo worked out a similar deal with Facebook last year, they are now signing up with Twitter for content sharing.
Twitter who has reached their 50,000,000 posts recently reaches out to many people daily. Yahoo has a focus on getting into the social media realm. Logging into your Yahoo account will be more social when Twitter is implemented into it. You will be able to view Twitter feeds, make status updates and more, right from your Yahoo account.
As you can see in the image above that Yahoo has already added in the Twitter real-time results. Things are moving forward!
