any one understand and use stumbleupon?

[Amumsim]

Hello, I have a wordpress blog and have looked signed up to stumbleupon. I just dont get it, I know the basic of what it does (shows me web pages with content they have linked to my interests) but I dont quite understand how it can help my blog!
Does my blog now become a page that can be stumbled on? If I press stumble on someones elses blog , what happens then - they get a vote? Is that it?
Can anyone explain?

sorry I don't know either. I know a fellow mumsnet blogger kindly said she was adding one of my posts to it, but I can't really understand it. Hope someone can help!

I've written about it here

It's a fab tool for driving traffic to your blog and for recommending other people's blog posts for reading to a wider audience.

Yes, thats what their website says, but how? Is it that basically if I have a stumbleupon button on my blog, then people can vote me up, is that how it drives traffic to me? I don't understand what it will do?

It's all explained in that blog post but, yes, you're "voted up" (given a thumbs up) and the more "thumbs up" you get, the more chance you have of your post appearing in general (non-blogger) stumbles and/or being featured in the StumbleUpon newsletter. It's a recommendation tool and a way to find new web content depending on which "side" of SU you're using at the time.

Whenever we've had something go viral at www.camelshump.co.uk it has always been Stumble Upon that has started it.

I have the toolbar, but I also sometimes use the app, and I try to remember to click thumbs up whenever I see something I like. I've found all kinds of cool stuff when stumbling :-)

Thank you Typecast, didn't spot you're link but I've looked it up now. I getcha, thanks!
