I think the feedback is helpful and there are always improvements that could be made. I think what really annoyed me was the underlying assumption was an entitlement to some sort of definition of an event that was perhaps too new to be fully defined. Good people jump in and help define the event.

I would not be critiquing a blog post full of specific, useful advice on how the event could have been made better. There is advice like that in this entry, but you have to reach through piles of raw "someone should have told me more about something" thoughts before you can get there. I would have been much more interested in a blog post that read something along the lines of: "I attended this event and I thought it was a bit unfocused. Here's what I would have wanted this to be and here's what I think it should look like."

I hope YC listens to the feedback anyway. It's valuable, but count me personally disappointed.
