The Gmail plus site says:
New! Gmail Plus Service is here
Gmail, meet Orkut. Gmail Plus (or Gmail+, as we like to call it) is the evolutionary next step for Gmail. With just one click, you can not only check your email, but meet new people at the same time. Connecting with other people has never been easier
Except the Gmail plus service is actually fake and been put together by a persitent code insertion flaw (Not just XSS but any content) that allows users to host a customised search service on the Google domain.
The Public Service service from Google is currently down with an error message, while I am sure they are fixing this, but unfortunately some more bad press for G is imminent from this particular flaw, but I must stand by my previous thoughts that "shit happens" and "what matters is how quickly it gets fixed" and G seem to be fixing it, but PLEASE take the Gmail Plus service down
