Well, I'm sure people at Dateline care, but it's probably mostly about ratings. Most of their "predator" episodes, which are their highest-watched shows, air during sweeps weeks.

While I think it's great what they're doing, I hope that the host (Chris Hanson is his name, right?) is careful. These guys who show up could be dangerous, especially if they've seen these shows and know they could possibly be set up. Mr. Hanson is usually only separated from the men who show up by a counter, and if one of these guys showed up with a weapon, he might be able to get in an attack before the police or others around there apprehended him.
