as science is usually thinking in alternatives: What is your alternative 
for TCP? Anybody is free to propose one.

In addition, I wonder, why we need Science at all. We already have 
Google and Wikipedia and obviously, research is no longer being done by 
academics or by some huge companies but by Google.

Brave new world.

Lloyd pointed out some criticism, and we should well remember the 
Hippocratic oath: "First do no harm." And thoughtlessly increasing 
initial windows or other "parameter changes" _may_ do harm.

On the quoted blog, we find comments like this one:

And whenever people are exited by simple recipes which save the world, 
we always should keep in mind RFC 1925.
