+3146 make someone share a link to your question on social media 
( see https://www.facebook.com/Web-20-scientific-calculator-204577902909300/ )
+3146 number of views from social media. (this might change in the future to the number of 'likes' of all social media posts referring to this question)
+1886 My suggestion would be to show the number of likes since there's a thumb up next to the number. Maybe use glyphicon glyphicon-user instead?
