Ouch. I do my own Digg submissions (
), but I usually let others do the rest of the networks. I don't do it for all my posts, just the ones I think people would be interested in. Mostly I hate putting up the Digg button with the Submit option... it seems like that would deter people, since they know they would have to make a new submission vs. just clicking the button to digg it and not having to go to another site.
