Do you use Google’s GMail service? I do, and love it. However a few weeks ago a “dot” appeared in the top left corner of the page. I didn’t think much about it at the time, as it looked like they were trying to make it look like a folded corner. As the days went on, I started to find the 10×10 pixel spot annoying. I constantly find my focus shifting to it.
On the 4th, someone posted a picture of the problematic pixels to Flickr, which in turn made it to Digg. Apparently there are many other people who find the spot annoying, and have their own theory as to what it is. Something to track page load speeds, tracking your activity, or as I though just a failed styling attempt. A number of people have also posted to Google Groups about it.
Even TechCrunch via TechCrunchIT is trying to figure out what this is. They’re even offering a free Tee-shirt (whoopie) to whoever comes up with the best, most entertaining, or most accurate theory.
