Right... he knows
I went back to his blog to see if I could find a way to put it into a reader of sorts, so that it would come to me by email. But nooo there's not button. There's just a Blogger follow button, which doesn't help me any because I have to follow as my own alter ego and he'll figure out who I am, or I have to follow anonymously, and be the FIRST follower on his site.
No matter. I went back, and there was a post wondering who one of his followers was. It went something like this: Who are the followers on my blog? I don't really care. If it is who I think it is, it's a bit of a surprise.
He must have a tracker that I can't see. I can't decide whether to tell him I found it. I think it would be the most honest thing to do. Or just ignore that it exists and never go back.
