I'm new to digg and stumble upon as i only use facebook and twitter for my website. Can anyone explain to me what is the main difference between stumble and digg? And also how digg and stumble upon get more traffic to your website? Thanks :)
DIGG and Stumbleupon have a different user experience, thus, the user have different expectation of the sites seen on these two sites. There are more actual visibility on Digg and more accidental visibility on StumbleUpon.
I don't see big difference between Digg and Stumble Upon. in general, both of them are very good bookmarking sites .. I would say the same as "dcc1" said; using both is better than using only one of them.
Good Luck !
