Well, Social Bookmarking involves many different aspects that can be looked after. For example, One digg submission from a Old digg.com Account with many friends added already will have a much better result then a new account. Since, I have been into Social Bookmarking and Link Baiting business since past 3-4 months now. I have learned that if you want to generate leads then you cant go for Social Bookmarking. Well, Social Bookmarking can help you in: Gaining Link Popularity Building a Brand name under few Lead Connections Help you gain authority over your niche region of competition Gain link backs from Authority Websites which helps new websites from getting out of sandbox effect. Chances of few and many leads, it depends on how you do it, in what way With my personal experience, I have had good luck building Link Popularity, even though every campaign which targeted articles written with Link Bait Techniques like CopyWriting, Viral Marketing, and other tweaks did got us many backlinks from different websites within our niche. Its a long brainstorming process, which if used with proper mind can get you that tipping point to touch skies

Yes, stumbleupon is really cool. And if you have some good story, then digg and slashdot also can give you huge traffic. Regards
