I will be the first one to admit that I don't know participate in the date aggregation point of the pipeline so my knowledge is rusty. Say one was designing a system where age, sex information was important. How do you keep track of this information:
1. Across multiple computers that the person might be using?
2. Expiring cookies?
Thanks
[Frictionless]: cookie + record in the database + random userid
[ForcedAccountCreation]: cookie + record in the database + arbitrary username + meaningless passwordhash
I can't think off hand of any advantage the things in that second list give you that you can't get from the things in the first one.
