Find out who makes you happiest on Facebook

Researchers at the University of Texas analyzed peoples' posts on Facebook and the emotions of those who read them, then an app was created to help people find their top friends.

The tool looks at friends and people with whom you appear in photos.  It also looks at posts you frequently like. 

Then, it compares posts in a status to lists of positive words and negative words.  It does not understand sarcasm, but the process has been shown to correlate to emotional content.

The University of Texas created the technology, known as Linguistic Inquiry and Word Count, according to an article TIME Magazine .

Researchers also found positive posts spike on weekends.  Around holidays the emotions run in both directions, positive and negative.
