I see. Then what are the possible answers?
Not being anonymous makes one visible (but without much access to it's online
activity).
Using Tor properly makes one anonymous.
My goal is to to keep my online activity to myself, even if it's possible to
know that I visit such and such website.
It's ok if it's known, but I want to succeed at that without standing out (a
paradox).
What is trying too hard, what is not trying hard enough?
I understand that it depends, but since my online activity is very basic (not
about anonymity so much, but privacy), I'm sure there's something that can be
done, and some things that I can forget about.
Libreboot,
a libre distro,
good browsing habit, specially when using Tor,
checking/changing the default DNS if it's google's,
no js or librejs,
destroy cookies,
no flash/java,
maybe a VPN,
That's some kind of checklist. At least, a starting point.
