Users may also take bookmarks saved by others and add them to their own collection, as well as to subscribe to the lists of others. - a personal knowledge management tool. Join them and post your story (submit story) samples of SB sites: digg.com propeller.com simpy.com fark.com reddit.com Hope this helps...

Social bookmarking will most likely only turn out traffic, most major social bookmarking networks use the ref="nofollow" tag, so your link doesn't help with SERPs, they are still good never the less since they send traffic sometimes.
Socialbookmarking is one of the good source of traffic.. It is more on tagging your favorite site and share it with other user for a huge list of it click here
I just started a site, and as of right now, bookmarking sites have been sending me around 80% of my traffic. I would suggest you implement this.
I actually put up a presentation for the ad agency i work for regarding social bookmarking. If you're interested, PM me with your email address and i'll send it to you.
