I'm planning to create a new cluster survey.
DJ don't hate me! When my daughter born i thought many things to give her, then she's 4 and more of that things are not so right....and i do new things now.
If we compile again (after 2 years) the survey, we kick off the duplicates, we are more "prepared" to answer, and we can ask more and better questions.

And do not forget that the statistics now assumes a normal distribution between ages. This is not true! the percentage of 18-35 yo on internet is much higher than 35-50, and this is much higher than 50-100. This mean, i gave an example:

if there are 20 CH on a total of 100 aged 18-35 on the board that say O2 function, and 35 CH on a total of 50 aged 35-50 on the board that say the same, the normal statistic say O2 function in the
55/150 =37% of the cases. THis is not right.
The % of WEB people between 18/35 is 60%
The % of WEB people between 35/50 is 30%
that means we have 2 times of weight on 35/50
Then the weighted percentage have to be:
((20*1)+(35*2))/150) = 60% of the cases
a big difference from 37%!!!

Let me know if you understand (not 'cause you aren't clever, but due to my terrible english)
I'm ready to start this new work on CH
Ciao everybody
