But in general you make an important point. In the
Hebrew Wikipedia
several
prominent editors adopted an attitude they call "Wiki A / Wiki B", which
they define more or less like this:
* To "Wiki A" belong articles that are likely to be used by students to do
homework. They should be as good as possible.
* To "Wiki B" belong articles about articles about pop culture, video
games
and sportsmen. It's a waste of time and mental health to try to get "Wiki
B"
articles deleted, but it's also a waste of time to get them improved.
Also, "Wiki B"-style articles rarely get to FA status in he.wp.
There should be also Wiki-C (rather, Wiki-9) articles which are about
specialized subjects too complicated for students such as advanced
sciences and humanities. They are may be even more important than Wiki-A
but are typically in a pitiful state due to the lack of qualified
contributors.
