When it's going deeper in the water wouldn't that make it harder for the duck to paddle forward, in other words: reducing it's speed?
Hm, that was perhaps off topic.
But I don't think that the site would be flooded with old threads coming to the surface as duck farts. Only those who still bear intrest to the community would survive, and mods could kick users in the n*ts who post "LOL funny" on all the random threads. In Cammys case it wouldn't be the problem, as she wouldn't post it, and there are no **** to kick either.
