S.F. SOMA-based Loomia.com, a syndicated search engine company with plans to offer web services in the future, is currently offering site users a limited number of registration invitations for people that wish to add ratings and reviews to content that has been accumulated and indexed on their site. They also feature videocast search in addition to podcasts and regular syndicated content which is new to me. Registration is not required to search for content, btw.

Additionally, if you get invited to join and you sign up, your account receives 6 invites to join the site that you can send to your friends. I just sent out an invite to a friend of mine.

Here's the link to their site.

I've got 5 invites left so ping me if you want one...
