That guy's like an automated troll poster to spam his site.
Anyway: Northwestern, Michigan, Pitt at the 7s. UCSF is supposedly starting it, it's +/- on whether the basic science in that division is strong enough to justify it. There are a few 6s with a year of research too, like MCW. Many programs say they're open to it without requiring it, so it's more of a thing if you want to avoid it.
You know...I was wondering about that actually. I saw some of his posts and I thought it was a bot. Then I looked over them, and realized they were "too personalized" to each post to be a bot. The link in his profile though, somewhat explains it.
