Spock Search Engine

so i've been checking out the beta of the Spock search engine and i'm not sure i like it.

it seems to be a hybrid social network/search engine as far as i can tell.

and it's just one more way for creeps to try and find out more information about someone.

i don't know if i think this is just a horrible idea or a valid search "tool" for end-users looking for information.

anybody have any comments about this new engine?
