An unexpected power law that relates site traffic to ranking by site traffic

How easy is it to estimate your number of site visits from site ranking and vice-versa?
Very easy: double the visits to halve the ranking.
I just blogged at upnaira.blogspot.com about finding the connection, and how rewarding to end up with such a neat graph:

Relationship between Alexa rank and monthly visitors

Here's the data I used:

Site	%Traffic Reach	Est. Monthly Visitors*	Alexa rank
yahoo	20	1000000000	4
craigslist	1.5	75000000	42
meetup	0.2	10000000	465
nairaland	0.08	4000000	1385
jobberman	0.02	1000000	4653
cp-africa	0.004	200000	44206
wemabank	0.00028	14000	557445

*The monthly visitors numbers are estimated by assuming jobberman has 1million visitors per month (I think that corresponds to a ranking around 5k) and that the traffic reach percentage (data given by alexa for each site) is simply number of visitors for this site / a fixed number corresponding to all traffic.  That is, take the traffic to be proportional to the traffic reach percentage.

Well, who wants to do this experiment on a large scale?
Plot Global rank against Traffic-reach % or Traffic-Reach-estimate-of-Monthly-Visitors and see how well the data fit this law.
Alexa.com ranks at least 10million sites, so you could test with that many datapoints.

Can you guess the movie titles?

You need to know a little math to figure these out!

A Summary of Mathematics

A lecture recently given at the University of Lagos was almost-verbatim published in The Guardian*.

In the paper titled Abstract Mathematics: Exploring the Universe through imaginative science , Prof. J.O. Olaleru gave a comprehensive layman's explanation of what mathematics and mathematicians care about these days - from number theory and topology to logic and even professional rewards: publications, prizes...
He said a bit about his own work and his beliefs as well.

Johnson Olajire Olaleru, PhD

Kindly download and read the paper:  Abstract Mathematics: Exploring the Universe through imaginative science .  It's a laudable example of maths in the public sphere.
