It is wise to make a note about the fact that such systems make it
possible to deduce earlier in the mean that someone is a vandal or not,
but it can't replace a good reader that responds to an error. This
creates the rather annoying situation where a response from a casual
reader should be weighted more than non-beginners, but this makes the
system suceptible to users wanting to skew its metrics on specific users.

Right. Also, we need to be clear what we want this to
do. It will
never be great at determining fact-checked material. What it is good
at is spotting the more dubious stuff, like possible vandalism. This
makes the possibility of having "most trusted" stable version as
discussed earlier. Small changes not only can be big in meaning, but
they still attest to the trust.
If I read a sentence to change some minor thing, I still read it. If a
wrongly says "he identifies himself as bisexual" or "born in 1885"
rather than 1985 in a page when I edit, I am going to revert if I
catch it. Even if just making some grammar/syntax cleanup. So each
time people look at stuff if still attest to the page a little bit,
from a vandalism perspective.
The algorithms can be made more strict to catch more general dubious
info better, but it is not that bad at that already, and the stricter
it gets, the more it gets under inclusive as to what is considered
unlikely to be vandalized.

If you want to pick out the malicious changes, you need to flag
also small changes.
"Sen. Hillary Clinton did *not* vote in favor of war in Iraq"
"John Doe, born in *1947*"
The ** indicates changes.
I can very well make a system that is insensitive to small
changes, but then the system would also be insensitive to many
kinds of malicious tampering, and one of my goals was to make it
hard for anyone to change without leaving at laest a minimal trace.
So it's a matter of goals, really.

One thing that stood out for me in the small sample of articles I
examined was the flagging of innocuous changes by casual users to
correct spelling, grammar, etc. Thus a "nice-to-have" would be a
"smoothing" algorithm that ignores inconsequential changes
such as
spelling corrections, etc. or the reordering of
semantically-contained
units of text (for example, reordering the line items in a
list w/o
changing the content of any particular line item, etc., or the
reordering of paragraphs and perhaps even sentences.) I think
this
would cover 90% or more of changes that are immaterial to an
article's
credibility.
