can be. but people on IRC are not representative.

I have about 10 courses of PL/pgSQL per year (about 100 people) -
almost all my students newer visited IRC. 30% of my students has a
problem to write a bublesort or some little bit complex code. I meet
this people. There can be a language barrier or some laziness. Really
it is surprisingly how too less people are interesting about coding.
This people has own problems, and usually uses a most classic patter
that know from programming languages.

These peoples are "normal" and typical. Some courses I have under some
big Czech agency - so there are people from banks, industry. Actually
only I do a courses of PLpgSQL in Czech language - so I think I know
what people use. For example - only a few people know and use a
generate_series functions.

sorry for offtopic :)
