Live Matrix – a TV Guide for The Web

Live Matrix is a new project by Sanjay Reddy and Nova Spivack. Spivack was the man behind Twine, a semantic bookmarking service, that was sold recently to Evri. Live Matrix will organize anything taking place on the web. Audiocasts, auctions, chats, MMO games, etc. According to TechCrunch they’re up to 80,000 scheduled events every week, and growing quickly.
Invitations for events are called “RSVP’s” (The term RSVP comes from the French expression “répondez s’il vous plaît”, meaning “please respond”. If RSVP is written on an invitation it means the invited guest must tell the host whether or not they plan to attend the party. Via about.com)
