My results differ depending on the browser.
The first search I did was in Firefox, logged in to Google, after visiting the site, it came #3.
I then tried on a different computer in Firefox, logged out, your site was not on page1.
Next on the second computer, in Chrome, logged out, history and cookies cleared, #3 again.
Then in IE, not found again.
This suggests that Google returns different results for the same query in Chrome than it does for other browsers.
