Its amazing what a simple google search will produce. Try searching for the following: linkedin directory people
In the result set you will quickly find this page which lists all the profiles that are set to appear in search results.
Try changing the letter in front of the .html to match your last name. For Susan Fischer its s.html.
You will then see further divisions of last name groups. Eventually you will find a list containing your profile.
If you see your profile in the list, make sure you are logged out of LinkedIn and click on it and see what everyone sees.
If there is information here you don't want just anyone to see then you may need to alter your lLinkedIn preferences.
LinkedIn recently had a password breach but its not the only company to have this happen. However being high profile it gets the press. This is a good opportunity to ask those companies that run sites you login to on a regular basis what they are doing to secure your information. If they don't have a plan or cannot tell you what they are doing then maybe you should stop logging in and delete your account. Also post a comment here on who they were so we can keep each other's info safe.
