If you are starting a new blog, or have one already, the best thing you can do is turn off all analytics. If you are worried about knowing when your site is “big” then worry no more. Trust me when I tell you: you will know when you site is big, with or without analytics, I promise that you will know.
It used to be fun to track hits to your blog. It seemed to be magic. “Look, someone from Japan is reading my post about iPhoto!”
These days — while still fun to see how your posts spread across the world — they can inhibit you and curtail what you end up sharing. Write whatever you want to write and do not worry about hits.
