There is a difference between brands of products that you use and have
experience with, vs. those that you may simply have no basis for knowing.

With your analogy I know that millions enjoy Guinness; me, I can't get
the stuff down! ;-) That's not to say it's bad, which it seems like
where your argument is going: recognized brand = good thing(tm).
Un-recognized brand = bad thing.

In the Schmoo thing, we both saw the cert details and knew rather
quickly that something was afoot because it was *not* Verisign. But I
see no way whatsoever that joe6pack on the street (joe6pack being
defined as a non-crypto geek) would have the faintest clue or even know
why he should care?   It's like me taking my car in for service. When
the mechanic says I need brake pads, I merely nod and say yes; we don't
even bother going through which brand he slaps on there because we both
know it would be meaningless to me. The only thing that's likely to get
my attention is when he asks "Do you want the $10 or $100 pads?". But
when I drive off the lot and my car successfully brakes, I quickly
forget the entire brake pad converation, not just the brand. For me it's
just not important. Just like most people haven't a clue what that damn
padlock is for anyway. Not on their radar. Un-unh. Nope. Not gonna happen.

We the crypto-geek community have to ensure that we give consumers the
necessary tools but that doesn't mean we need or should attempt to make
them experts. For no matter what clever hack we code, RFC we write, or
GUI we display, it boils down to Abe Lincoln's "You can fool all of the
people some of the time, some of the people all of the time, but you
can't fool all of the people all of the time".   We can only address
parts of the argument IMO, not the whole thing.
