Is there a plugin that lists social network links?

Is there a plugin that can be used by a blogger (not the members who register) to automatically create a page (with icons) of all the social networking sites they’re on? I saw something like this used for registered members of the mashable community and there is something like this implemented via an app on facebook. The links/blogroll could do this but one cannot add mini-icons to the links/blogroll. Is there one that automates this?
