Is there a way to add to or remove from the list of Social Bookmarking entries? I see a lot of entries I've never even heard of, while I don't see LinkedIn which is the most-widely used professional social media tool in Holland and Belgium (and probably in many more countries). 

Please advise.

Hi Peter :
Of course , you can add and remove from the list.

The steps to add :

1) Go to Administration

2) Third Party Software

3) Social Bookmarks

After tha you can see the code that you need for every social network site.

For ejemple for facebook :

http://www.facebook.com/share.php?u={LINK}&t={TITLE}

You just need to "Create" another social bookmark, the code for Linkedin :

Title : Linkedin
Link : http://www.linkedin.com/shareArticle?url={LINK}&title={TITLE}

Thast all, fast and easy.

Enjoy it
