Any similar traffic sources as stumbleupon?

Stumbleupon, as you know, is a site that helps people find new sites, and can ultimately bring in a lot of traffic quite simply. Are there any other such sources of traffic? It doesn't necessarily have to be targeted, like stumbleupon.

Thanks.

 

There are hundreds of lists in the net, try this one.

List of social bookmarking sites

 

I'm aware of social bookmarking sites, but stumbleupon is different. People don't need to click on a link to access your site. People click on a "Stumble" button and automatically come across your site. Is there another system such as this? Or any other way where traffic can burst?

Thanks.

 

yes before stumble upon

there was traffic exchanges..
you view my link i view yours
then came autosurfs..
after that paid to autosurfs

and now stumble upon

 

Good point.

There are loads of digg clones but not nearly as many stumbleupon clones.

Nothing I can find works exactly like stumbleupon, but there are a lot of good social bookmarking sites. Try your luck with one of the $3 for 30 social bookmarking submissions, you may be surprised.
