I prefer scrolling through the interview feedback threads, too, because it's easier and more efficient to skim through and glean what information may be helpful. I also think the form contains information that is unnecessary (e.g., how many hours did you spend traveling? But there is no information on where the person started his/her trip from so it's never relevant. It isn't going to change how many hours it'll take me to get there from where I am, or influence my decision to apply to that program). Also, I like the threads because what matters most to me are not what comes in those fields with pull-down menus, but in the written descriptions about the interview experience. Some of the feedback posts, I've noticed, are partially filled out but don't have descriptions.
That said, I will post reviews on the feedback page when I get a chance next month. I do appreciate that people have posted their impressions already. Many of my interviews are in December with some in January. Good luck to everyone during these next few months!
