With Pulse (screenshots at bottom), each Plaxo user will be able to view their existing contact lists organized according to business, friends, family and other categories. It also includes a view of a stream of RSS feeds people whose contact information you already have in Plaxo.

Pulse uses Plaxo’s existing method of sorting contacts into business, friends, family members and other categories. The company launched a calendar service in late June that we noted looked similar to the event management feature of Facebook.
