Plaxo released version 3.0, a public beta. Plaxo is like an aggregator for your calender and contact lists. Instead of keeping a Gmail, Outlook, Yahoo, AIM, Yahoo! and a variety of other contact list/calendar/task manger services, Plaxo combines them all in to one service. A svelte looking AJAX interface, fairly similar to Google Calendar allows you to sync all your events to one place and take them with you. It's a fairly novel idea if your on the go and try to keep work and personal time separate but at the same time, in one place.
