Yeah I\'m like half way through it. It\'s cool and makes my basic html knowledge look like dark ages shit, heh. If it can interface with Outlook and other email clients (and maybe it does, I\'m not done with the vid) it could be useful, otherwise it\'s another glorified Facebook/Twitter/whatever social networking thing.
It\'ll be yet another "necessary" web add on unless people can use it exclusively instead of email, so hopefully that\'s the goal. There\'s too many "necessary" social sites out there sucking up work hours as it is.
