Bookmarking....

When someone Diggs, or Stumbles your post via the social bookmarking plugin that you have on your blog....what happens when someone else Diggs it again? Does Digg automatically direct them to the page where it was already Digged, so they can give it a second Digg? or does it put the articles as two separate Diggs, as if they were different articles?

 

I think that they cannot Digg it again & a message will appear that the story has already been Dugg

 

Any people can digg those having individual login id with digg and the number of digg will be shown there beside your post.
