This may or may not be successful, but I'm gonna try anyway.
A user will post a wish related to the DB franchise; then a different user will reply and corrupt that wish, and then state his own. Then another user will corrupt the above wish and state his own. This will continue until the blog dies. Users can make another wish, but only when someone has already corrupted their's.
e.g
User 1:I wish DBGT would never happen.
User 2:Granted, but then Z will have a crappy ending. I wish most DB games were good.
User 3:Granted, but all other games will suck. I wish for BT4.
User 1(again):Granted, but it'll only include Goku and Gohan. I wish for a new DB series.
Update: If a user does not make a wish, but just corrupts one then the user who replys will corrupt the same wish the previous user did and make a wish.
e.g
User 1: I wish DBGT would never happen.
User 2: Granted, but then Z will have a crappy ending.
User 3(answer to User 1): Granted, but then the whole DB franchise will never happen. I wish for BLARGH.
And so on
