Chris, since you have probably already read Eliezer's comments
(if you haven't you should follow the links from extropy.org
to the archives of the last week or so), I'll simply comment
that some of us are fairly neutral regarding approaches to
different aspects of AI (and will freely admit our lack of
knowledge with regard to much of it).
So, stating my ignorance in advance, I'll simply make a few comments
on your comments:

While I can understand reasons for doing this, it will leave a bad
taste in the mouths of many with an academic or open source perspectives.

I'd say this statement is flawed from two perspectives. First, if you
have no verifiction of the "reputation" of your "humanness" sources you
have no controls on the results. You are going to get much different
results if your humans are Jesuit priests vs. modern-day neo-nazis.
Presumably you get a slightly more intelligent and affluent cross
section of humanity (i.e. the people net-connected and producing
the inputs to your system). That would seem to imply you are going
to get a pretty "average" human perspective out of the whole effort.
Producing more "average" humans isn't of much use from an extropian
perspective. We have more than enough problems figuring out how to
feed the ones produced using the regular old-fashioned manufacturing
methods. Second, there seems to be an implicit assumption that using
current "humaneness" can evolve an artificial consciousness. Leaving
aside the meaning of the suitcase term "consciousness", the
problem may be that for humans to have reached that state they
had to go through their entire evolutionary history. Modern humans,
not knowing how to chip flint or stalk a mammoth, may not be able
to regenerate "consciousness". All you may end up with is a machine
able to pass the Turing test, but still not be "conscious".

That's 20 real "average" people.

You can get 20 real average people to confirm a belief in God --
getting a combination of a database and some statistical analysis
software to do the same doesn't make God any more "real".

I don't know much about Open Mind, and only know a little more about Cyc.
I would not classify Cyc as trying to collect human "consensus" information.
Human "consensus" information is often wrong and I doubt Doug would be
building wrong concepts into a common sense database. I'd classify Cyc
more of an attempt to get the commonly agreed upon as scientifically correct
information into a database with an attached reasoning and inference engine.
I would agree that GAC may be interesting social science, but I
deeply doubt it will produce a useful path to an advanced
artificial intelligence. Since an advanced artificial intelligence
is what most extropians would find of interest, the approach
isn't likely to find a warm reception here. (But you probably
have already figured that out...). What might be interesting
at some future point in time is to watch a Turing test between
Cyc and GAC. It could reveal some very interesting insights
into the many false beliefs that most people hold.
I'd suggest you consider the problem of how one would build into
GAC the concepts of "trust" and "reputations". A quick search
"The Production of Trust in Online Markets" by Peter Kollock
which references some of the early work by Miller & Drexler.
I've got little interest in knowing what the average human knows.
I've got a great interest in knowing what "high" reputation
