How does StumbleUpon help me?

Unlike other social media/networking sites such as Digg, I do get traffic from users clicking on links to my content at StumbleUpon. Muhammad Saleem at Pronet Advertsing may have explained why.

Both Digg and Netscape send almost zero traffic until you get promoted to the sites’ homepages……On the contrary, you only need 3-4 thumbs of approval from Stumblers before a decent number of visitors start coming in to your site. The more ‘likes’ (thumbs up, or votes) you get, the more traffic you will get.

People often discount StumbleUpon because the traffic spikes aren’t as sudden and as huge as those resulting from Digg. While it’s true that the spikes aren’t as huge, if you look at the total traffic trends over longer stretches (i.e. a week or two) you will see that the visitor count equals out.

But I’m stupid. I can’t really figure out how I would use StumbleUpon to network with members who would cite my content and me theirs. The people who cite my posts on the blogosphere, in effect promoting me by word of mouth, are lawyers, marketing & PR professionals, journalists, students, and the like.

Would it be possible to network with folks like this at StumbleUpon? If so, please tell me what I am missing. If I am missing how StumbleUpon works, let me know that as well.

I’d like to know and so would the lawyers and legal marketing professionals that I advise.
