Spock the people search startup has a spooky way to verify your identify. I find it hard to give away my password to another site (linkedin in this case) to verify my identity. I'm brainwashed to not trust anything or anyone who ask me my password. In this case they say it's to verify my identity, but what do they do with the password afterward? There ought to be a better way - I haven't checked LinkedIn's API, actually it looks like LinkedIn doesn't have an API just yet.
