Because his name is not clickeable it means 100% of the people that is interested in him had to google him. So it's pretty easy to measure it's impact.
So it's impact augmented by a factor of 20; if he was searched 10 times per month before it means now he is being searched 200. So not that much but even if it were your point still doesn't make sense to me because what difference would there be with anyone writing anything? I guess that your point is not that everyone should write anonymously right? So, what is it?
