It's not the voting user that Digg and Kirtsy are using for "Username made this article popular", the username is from whomever submitted the article. They are giving a timestamp to each article when it gets pushed to the front page. This took some modifications to come up with and isn't built into Pligg. If you just want to show who submitted the article followed by how long ago you can just tweak the language file and link_summary.tpl.

I think adding "made popular X time ago" might be something I will add to the feature request list.
