Mike, till now you've made serious arguments. But quite frankly, firesheep
is just a joke to send the usual summer end-of-the-world alert to the press.
I think none of us knows anybody who's been victim of this, because where it
would have mattered, TLS would have been used anyway.

I'm concerned about the situations where users' security is really attacked,
which is massive MITM using fake certs, massive bank accounts and credentials
collection using malware, spyware returning your browsing history to ads
vendors, and more recently malware running on smartphones to collect a lot
of personal information.

Mandating use of TLS is irrelevant to these real world issues and can only
make them worse. However I agree it will feel good to say "hey look, now I
can show you that firesheep doesn't see my cleartext password anymore",
but what site would require me to send my password in cleartext over the
net anyway ?
