Google Dance or is it crap?
I was just checking my blog statistics and clicked a few Google search links from with the stats. Accidentally, I clicked the same search phrase twice. I was about to close the duplicate tab after seeing the first tab, that I noticed the two of them weren't exactly the same. So I went on to see them in details. Apparently it was just a switch of two of the search results in the two pages. Have a look at these two screenshots I took.
I first thought that it was an effect of a change in PageRank combined with Google Dance. But then saw the number of results in the top-right side of the page. It was showing 5,250 in the first page and 14,500 in the second. Oooh! So this isn't just what I thought.
