Perhaps the answers would have made more sense if everyone knew exactly 
what the question was.  :)

You asked for an estimate of the "size of the Internet", but didn't 
specify if you meant number of networks comprising the Internet, number of 
devices connected to the Internet, combined total transit for all ASNs 
connected to the Internet, etc.  The nature of the Internet is that nobody 
knows the answers to any of these questions.  How do you know what goes on 
in my networks?  So any "answers" are really only wild guesses.
