I need a plugin to show "top bloggers" on my multisite... Is there any plugin that can do

I am doing a site that gives users the ability to sign up and create their own blogs. I am currently doing the home page of the site and I need the ability to put top bloggers on there... I could not find any plugins that suit this need, which I found very odd... all I found was the widget for setting random or recent users... even having a plugin that can show a custom list of users would be great.

Any help?
