No, it is not.

For most individuals who really *need* (as opposed to those
that do it as a matter of ideology or principle) to protect
their communication, the need to keep confidential who is
communicating with whom is as important as is the protection
of the content.

Current "secure computer communication systems" do nothing
for them. WoT is actually a complete antithesis of their
requirements. This is probably why, after all these years,
the fraction of encrypted e-mails remains so minuscule.
Encrypted e-mail between private individuals is today the
province of the enthusiasts instead of those who are in the
need of it.
