CHICAGO TRIBUNE – Oct 31 – LinkedIn can serve as a toolbox for searching online ahead of dates. For example, finding out whether those who proclaim themselves successful business owners actually own one, or simply confirming whether people are employed. One app sprang up using the site. BeLinked, previously known as LinkedUp, targets career-minded singles and operates by importing users’ LinkedIn data, then making matches. Founder Max Fischer launched the site when he noticed that his friends would subtly begin conversations with interesting people through LinkedIn.
