Sorry I completely disagree here. Even a 10 DNS queries from my PC to 8.8.8.8
from the same temporary IP addr will allow far end to compare to a database of
fingerprints and spot me as the only person using those 10 URLs concurrently
and maybe even in this particular sequence. Add to that the usual ubiquitous
google adds that appear on every website you surf to, the DNS queries your
different services like IRC and mail client do and you don't need any gmail
account or "google for something" to give away a *complete* profile incl
timestamps of *all* your activities on PC to 8.8.8.8 statistical analysis resp
data mining.
