When you want to know about a domain name, you jump to whois to get all of the information on the person who registered it. But when you want to know more about the person who just started following you on Twitter or FriendFeed, it hasn't been that easy - even though we've tried to provide you with tools to do it. Now, a new service promises to simplify the process. It's a new take on whois for the social web: SocialWhois, a service that uses XFN, microformats, APML, and tagging to provide a more complete picture of that new follower's presence online.
