Retaggr: sharing your portable online profile across social networks

"retaggr [was before it closed] a widget-based service that enables active web users to link all their various site-based profiles into a single, always updated, interactive business card that can be attached to virtually any type of content or interaction the user has on the web.

The interactive profile card can be linked to or embedded anywhere online, including in email signatures, blog entries, other text, or as part of online profiles on sites like LinkedIn, Facebook, twitter, and others. It lets you leave a summary of the way you define yourself on the web anywhere you want to share it."
