Post making contest 3.0

So here's what I think right now:
Rule 2: Post must not be edited before being evaluated.
Rule 4: Post must link to itself.

Given that, I think we should try to work out the ruleset and then worry about making a winning post at a time when nobody else is posting.

It's unclear what sort of predictions count for Rule 5. The next post will have a guess at Rule 5's conditions.
