Wall Street Journal adds to the list of new credible sources releasing Facebook apps with “WSJ Social.” The clean and well-organized interface sorts the top stories and columns of the day into easy to read categories. Your news feed allows you to sort your favorite editors. As with other content, you are afforded the opportunity to like and comment on stories, aggregating them according to your interest. The journal has also introduced a Youtube video which, besides tugging at my heart-strings, also chronicles the journey that news sources continue to make from tangible to electronic. Long live the printed word.
