Some of it Marc has already touched on. When we invited Facebook, they said no, and they're not going to change and they are Instagram, so it's the same company. Twitter has already been asked to appear, and are coming, so we can certainly ask them about that when they're here.
Personally, I would prefer to hear from people who actually can explain algorithms and how they work and what they are and what the federal government can do, if anything, around that as opposed to the people who are running these sites.
If there are experts out there—and I can't tell you right now who they are—who can explain what it is, and if there's anything a federal government can even do to regulate it.... We could very well find out that there isn't.
I don't know, but I think as opposed to bringing in all the people who are providing, like Instagram and BuzzFeed, I would much rather have some experts come in, whether that's in a department—I'm not sure that it is—or whether it's academics, but someone in the country who can speak to that and give us some guidance. I think that would cover what we're looking for, which is how we deal with these algorithms and what we can do to rein it in.
