Plaxo

Plaxo is trying another way to keep your address book update. The service is only for Windows Outlook users, which is a pity. Plaxo helps you to request updates (by email) from people in your address-book. If some sends you an email update your Outlook address book is updated. What happens is that this information is also stored at Plaxo. So the next time an update of that person happens all related address books are update as well. In this way Plaxo slowly builds up a database and its relations.

Sound pretty smart. I would however prefer a P2P solution based on Foaf.
