Maybe this will give you a better idea of a good use for this.

At my site, Tech-Unity
The site is mostly for people studying for a Computer/Networking Certification

I am provided questions by a few well known companys, Transcender, Redmond Exams, StudyExam4Less.

I post questions once a week, around 8 to 10.
when people reply to the question with whatever they think the answer is, they put it in this hide hack.
The next person coming into the thread cannot see his answer until (s)he replies, basically keeping human curiousity (some may say cheating) down to a minimum. I also have the spoiler tag set up for people that want to give users a hint (but not the answer).

at the end of the week I post the correct answers.

Granted this isn't perfect because people could reply with anything, just to look at the other guys answer then edit there post to put the correct answer, but, I have to use an honor system at least.

Example

Anyway, I hope that gives you a better idea, as to why you would use this.
