Driving down traffic

I'm still trying to drive down the traffic on my site, and closing it to search engines didn't completely solve the problem for some reason, so I am closing some of the more popular posts to password-protected posts. But don't worry, they are all quite old, and if you really want to see something, the password is whatever the title of the post is. For example, if I wanted to protect this post, I would make the password 'Driving down traffic'. We'll see if this helps me get a bit less visibility.
