Why do we get rep points on associating our accounts?
What is the purpose of giving reputation to existing users when they join new SE sites anymore?
With 100 reputation I can't downvote questions and I can't create new tags. What purpose does it matter that I get this reputation now, that I can comment?
Without being able to downvote and add new tags it almost seems pointless to value that people are existing stack exchange members. You might as well just start them at 0 then.
