Bloated Expert

Don’t you have an expert in your contact list? I can’t believe it. Mr. know-it-all is a bloated user that don’t miss the chance to show off his 360° knowledges. In spite of his competences he got a lot of time to spend on social networks and you would ask him: “if you are so erudite, why are you full-time on Facebook?”. http://di-side.com/blog/social-media-users
