I noticed that I broke into the top ten post on WordPress yesterday.
If you had wondered what are the stat. thresholds to get to that degree of observation. Here
are what mine were.
My post of the day topped out at just under 1,926 hits. My blog had a 2,396 hits.
Number one could be many times that number I imagine.
I would guess that that is probably what you would need to get into the top ten. In time that number will likely only go up as WordPress continues to press ahead.
