i am barking on the list; whoever is the appropriate person to react,
has the chance to read and react. i don't think it's appropriate to
send my messages to x or y personally. what is the right tree, you say?

i discussed these things with you, because you responded. this made me
think you were not indifferent, but anyway i kept ccing to the list
precisely because because i don't think you're the right person to make
a decision or suggest the next steps.

why not read some fortunes?
"When a Certain Guru rips strips off people (God knows he's done it to
enough) on this list, there's a damned good reason for it.

more 'customer service' attitude than R-help was needed)

when gurus are ripped strips off on this list, there's a damned good
reason for it.
(and i'm actually not doing it.) or:
"You may have not been long enough on this list to see that some of the
gurus have reached a demigod like status. Demigods have all rights to be
(that's almost a definition of a demi-deity).
-- Jari Oksanen (in a discussion on whether answers on R-help should
R-help (December 2004)"
which certainly documents a very productive approach to communication

a few over the years?

your sampling window does not seem to provide better results.

ah, so what's the difference between the way i pinpoint design flaws and
the way r gurus respond to people, so that i am running with a chip on
my shoulder, and they are being 'negatively motivating/reinforcing' in
didactic terms? (am i correct, is the 'negative
motivation/reinforcement' the same stuff jari oksanen talked about?)

was this really running with a chip:
"shouldn't the tests have captured it? i think you should have a check
for every feature following from the docs."
to which marting responded "yes, we should"

haven't done the thing.
