Restrict reading a thread... until member quickreplies?

[Tralala]

I am asking for feedback in a forum but I want folks to have to post first before being able to read anything (past the first post in a thread.)

I don't want them replying to each other, rather, I want them to have to provide feedback of their own without being swayed by previous posts.

Is there a hack for this? Is it possible?

It's sort of like, seeing the results of a poll. You can see them until you vote first. Well, I want to do that with a thread's content. You can't read post 2 and beyond, until you reply first. Is this possible?
