LinkedIn wants users to sign in to see anyone's profile. what is seen is defined by the user. LinkedIn is behind networking data. who sees who, who connects to who and how are the connections and relations impacting.. etc.. so they are not for showing anyone profile for the public. that is the new business model. this news is mistitled, Linkedin is not anonymous anymore.
I wish Google would obliterate their search engine ranking for redirecting you to a login screen that does not contain any of the text from the preview
