Thank you for your honesty.

The sci nomenclature in the name of the newsgroup ought to give
you some hint that this newsgroup wasn't originally organized for
publike discussions despite the fact that several here seem unable
to rise above that lifestyle.

Try alt.* or alt.sci.* and rec.* if you like those sorts of
discussions. Living in oz you might also like uk.* groups.

You can expect the sort of question I asked when you participate
in the sci newsgroups. Were this sci.physics you'd have had your
head handed to you in an ascii basket by at least half a dozen
posters.
