riffenberg on "Wordpress referrers have dwindled,doesn't show up in search"

It took me hours to find out how to ask a question. Ok, here is the question. I used to have a lot of WordPress referrers from automatic links. Not anymore. Plus I don't have very many automatic links on my posts. Why? Third my posts don't show up when I use the same tags as someone else. They are no-where. Example, my last post.
