LinkedIn is one of popular http://knol.google.com/k/rajamanickam-antonimuthu/social-bookmarking-sites/14dmp09oqdm08/115#. I used to show my LinkedIn profile in many places including my blog and email signature. Even I used to send email invites to the people who are in my email address book. Yesterday also I had sent many email invites. But, starting from Yesterday evening I couldn't login into the LinkedIn Site. It showed error message "Access to this account has been suspended" Now, the people clicking this profile link will see "Profile Not Found" message. We can understand the Danger of using our LinkedIn profile in our blogs and websites. So,think twice before showing your LinkedIn profile in your blogs and Websites.
