No idea, sorry. What is the point of all these questions? Are you trying to say there are more anti-McCann sites on the internet than pro ones? Does that mean anti's outnumber pro's then, do you think? Or could it be that the 'anti' viewpoint is only able to be presented on the internet due to the McCann stranglehold on the media.
If you understand real journalism, you will know that it has to be an unbiased presentation of facts. MSM is only allowed to publish information which does not compromise the ongoing investigation in any way. That is not, as you put it, a McCann stranglehold.
On the internet, however, there is a plethora of unregulated propaganda, orchestrated by sceptics, often on an almost daily basis (hence you cannot immediately direct me to any pro-McCann blogs). Most supporters have already educated themselves simply by reading the files and need no prompting to do so. The same cannot be said of those who still believe in syringes & disposed refrigeration products.
