The count is based off of HTTP HEAD requests. A quick way to test this is to run "curl -I " from a linux or mac command line. I noticed that most of your time your site returns a 403 Forbidden:
$ curl -I http://www.icedchai.com/countries/our-night-climb-and-the-sunrise-at-mt-sinai/
HTTP/1.1 403 Forbidden
Date: Thu, 13 Oct 2011 16:42:31 GMT
Server: Apache
Accept-Ranges: bytes
Vary: Accept-Encoding,User-Agent
Content-Type: text/html
$ curl -I http://www.icedchai.com/photography/photos-luxor-temple-at-night/
HTTP/1.1 403 Forbidden
Date: Thu, 13 Oct 2011 16:43:48 GMT
Server: Apache
Accept-Ranges: bytes
Vary: Accept-Encoding,User-Agent
Content-Type: text/html
One strange thing was that one request actually did succeed:
$ curl -I http://www.icedchai.com/photography/photos-luxor-temple-at-night/
HTTP/1.1 200 OK
Date: Thu, 13 Oct 2011 16:42:45 GMT

The inconsistent counts are probably a result of your server returning random success / failure messages in response to HEAD requests.
