For those of you obsessed with the stats, I found this yesterday and what I really like about it as well as being free, you can set it so it's invisible so people can't see it on your blog, I had a comment from someone who didn't like the visible Feedjit thing on my blog, found it off putting, I suppose because people want to feel they can look at my blog totally anonymously if they want without me knowing who they are. It seems to have an amazing amout of detail and easy to put on a blog as well.
