As others have already said, I guess it's the repository of content. I watched Heat and Cape Fear for the first time yesterday, and then spent like an hour reading random threads about it. And I could have easily continued! And there are movies with an endless supply of huge threads, like Eyes Wide Shut.

This is just an anecdotal example that I just lived yesterday.

Is there really such a big influx of users migrating specifically TODAY, of all days? I guessed most interested users, like us, did in advance these last 3-4 weeks.

I wish there was a way to see the traffic of different instances in (mostly) real time.
