I think people thing US-CERT is more important than it actually is because of its history, which included a long stretch where it was the only incident response team anyone had heard of. But in reality, US-CERT does very, very little: it is a clearinghouse for heavily redacted vulnerability information that has usually been in the mainstream for a long time.
Did you read the definition of cyber threat information in the bill? It's here: http://intelligence.house.gov/hr-624-bill-and-amendments
If so, I'd be interested in your ideas for improving the definition.
Thank you for the thoughtful comment.
