Social bookmarking has 2 main benefits:

First let's look at what social bookmarking is. Social bookmarking sites were created for the user to have the ability to bookmark all their favorite sites in one place, therefore if your PC crash or if you are on a public PC you will always have your bookmarks handy in one place.
Social bookmarking sites also makes it possible for members to view other members bookmarks. This is where most marketers make the mistake, Digg, Stumbleupon etc is a social platform where people share their different interesting websites that they find on the net.Now if you go and bookmark only your own sites or just salespages then you can be seen as a selfless spammer and that you don't contribute to the community.

It's the same as being here in the forums,Nobody is going to take you seriosly or do business with you if you just post things about your own business or product in a spammy way. Bookmark all kinds of sites in these bookmarking sites including your own.You want to be seen as a normal person and normal people bookmark all kinds of different interesting websites.

So the first way to benefit from social bookmarking is to make a lot of friends on the different social bookmarking sites, comment on their sites and participate and the members will start doing the same for you.

The second way is to help with building backlinks to your site. Some of the social bookmarking sites is do follow while some isn't. You can go to Social bookmarking service. Fast tagging and posting to all major social websites - SocialMarker.com and see which ones has a do follow policy.

Hope that helped,

Cheers
