whoisi

Whoisi provides rich site summary solutions that help users track others’ online activities.

whoisi is a site that lets you easily keep track of what your friends are doing on the Internet via RSS feeds. The site is organized around people. Everyone has an entry that gives an overview of what they are doing on the internet. But that entry is created entirely like a wiki. Anyone can edit anything. It's up to followers to keep track of their friends and the accounts they happen to have.
