I have added my site but it is not showing up in the Top Site List. Why?

Your site will not appear in the list until you have installed the Top Sites Button on your website (on a live server). In addition, in any week where your site does not generate any button impressions, your site will not appear in the list. This is to prevent the site listing “dead sites” that people have added but never got round to adding the code to their site.?
