My suggestion is whether a Freeze/Hide functionality would be useful within the 1-5 minutes of a new Question/Answer?
What about a "preview" grace period where people can vote on something, but it doesn't show until the author has expended his/her "edit time"?
I answered a question with some code, knowing it would work. However, I noticed a bug and so needed to compile the code and double-check it. Not wanting to be down-voted, I actually deleted my answer so no one would be able to see it. Then, I did my double checking and 5 minutes later I undeleted my post and edited it with some run-time checks/exception handling. This seems like overkill when all I wanted was to "hide" my answer for a little while.
