Linked<br>I tried to do some work yesterday. I had to use a linkedin website. After I was done, people starting adding me. I was confused as to why they added me. I realized it was because I had been logged in.
LinkedIn is not a social networking site. 
( z1 site :polarity - :mod ( z2 social ) :domain ( z3 publication :name ( z4 name :op "LinkedIn" ) ) )
