My sincere apologies Adam, I was not trying to make you into the
villian of this, and probably should have worded things differently.
The poll was done in a sincere effort to get information. And some
sort of poll is needed to start seeing what questions need to be
asked. However an initial poll like this only has a confidence level
of around 50% and no ability to do confidence levels (+/-X amount you
see on various polls in the news)
The results from it have been parlayed as facts; when in the end, they
are just a viewpoint of a select view of people (those who register on
the forum, use the forum regularly,etc ), and because of the nature of
the forum it is hard to determine how much validity there is in the
testing. Even if it was not stuffed, the uncertainty of the tool makes
it so that if say the slower updates had been 70% of the population,
the other side would claim it wasn't a valid test (and vice versa).

No we would have to determine it from FAS... probably using the group
CLA and been a member for over X time. You would then poll through
them sending a directed email to a random set and point them to a
closed poll. After the poll had been validated you would then announce
the results (or announce that it had failed validty tests).
While the FAS+CLA is a self selected group, it is representative of
the developers of the group which would fit into the population that
both groups seem to be thinking they talk for

Ah, but a man's reach should exceed his grasp. Or what's a heaven for?
