Conversely, if a cultural touchpoint shared with millions of neighbors isn't worth writing about, what is? Wikipedia isn't a newspaper so most current events probably aren't worthy of long-term documentation. There are more bands and songs than actors and movies. WP doesn't aim to be a summarized mirror of scientific journals. And yet it contains a little bit of each of those because someone thought they were worth writing about.

I'm asking seriously:

1) What's the problem with every movie (or actor or song) having its own page? They're not all linked from the front page, so they don't pollute WP any more than the existence of some rando's blog dilutes the Internet experience of people who don't visit it.

2) If movies (or actors or songs) aren't worthy of documentation, what do you feel is?
