Spotback is now in public beta

Spotback which advertises itself as the "rate everything!" platform for the web 2.0 is finally out of private beta and available to the public.

Spotback provides widgets that blog writers can embed in their blogs. The widgets enable readers to both rate blog posts and see which blogs posts have received the highest ratings from others.

Spotback users are also provided with a personalized recommendation service that takes their past ratings into consideration - a bit like outbrain.com.

I haven't given Spotback a "run for their money" (note that the service is totally free :) ), but it sounds promising. Their public launch should spice up the competition in the emerging arena of personalized rating-based content.
