Who bookmarks your blog post is important: more or less traffic

Bookmarking blog posts

Blog posts and stories can be bookmarked on Digg, StumbleUpon, Mixx, Propeller, Reddit and several more for their:
- Content
- Information value
- Title
by registered people.
Although this is called social bookmarking seemingly to reference to consumer market, it also applies for B2B.

Website traffic

Getting a blog post bookmarked will bring traffic: from a few clicks
Getting a blog post bookmarked by a notorious bookmarker, will bring even more traffic: to thousands of clicks.
Notorious bookmarkers have a certain status and are trusted for their quality links by their followers and thus generate more clicks.

As an example Digg has 30 million users per month, but their member user base is only 3 million. Of those registered a significant lower number are actually Digging posts, news and articles. Thus a fairly low number of people are guiding what all the others are reading. And some of them are much more notorious than others.

This creates the problem of the taken link:
Once a link to a blog post has been bookmarked it becomes blocked for others to bookmark.
Thus if you have bad luck and your great blog post gets bookmarked by a “Nobody” then you will get much lesser visits.

Still a catchy title and good summary can propel the story forward, but your story has started with a handicap.

Voting blog posts

In most cases a bookmarked link by a notoriety gets more votes as they just attire more attention due to their trust status.
Those more votes will generate even more traffic over a longer time span.

Thus you need luck in the bookmarking game for getting bookmarked and getting bookmarked by leaders.

Warning:
In any case never ever bookmark yourself as you are probably a “Nobody”. Thus less clicks to your website, less votes and you take away the opportunity for a notorious bookmarker to bookmark.
