I need to know the difference between to types of social bookmarking.?

I am doing a powerpoint on Social Bookmarking and Social Bookmarking in the Enterprise. It’s to my understanding that Social Bookmarking is a site that provides you with an easier way to save and organize your favorite sites. Now what’s the difference between doing just that and doing that in the enterprise. Thanks!

If you do it in the Enterprise, then Captain Piccard and Lieutenant Commander Data could Socialize with the bookmarks together with you, but if not, then you would have to do it alone, I think…
