Encyclopedias are not designed to report on pop culture. The entire nature of an encyclopedia is to be downstream of good secondary sources, ideally academic, and summarise what those good secondary sources have said about specific topics.
Side note, it is very funny that the same people lamenting the state of Wikipedia seem to be desperate to have their topic included on it. If the site sucks, why care about it so much?
It's funny. Today people say that of Wikipedia, as if it was trustworthy. But it used to be common knowledge to just "don't trust anything on Wikipedia". Wikipedia was never like a regular encyclopedia, it just wanted to be one.
Its biggest advantage over traditional encyclopedias was its breadth and how quickly it could be updated. The trade-off was that articles could vary greatly in quality and could be edited by anyone, making accuracy less consistent than in traditionally edited reference works. So the effort to reduce breadth and say it shouldn't be updated quick... that's just strikes me (as someone fairly old) as kind of funny.
