Alexa's numbers are all weird. If, based on their info, you map out last month for the top 20 you would have:
no one at spot #7
Wiki and Baidu at #9 tied
No one at #10
No one at #12
Rapid and qq at #13 tied
Friendster and Microsoft at #17 tied
18 and 19 would also be blank but they could be from names dropping out of the top 20.
I doubt very much that there were ties in the previous month for a spot much less three spots.
