Well, that's precisely the paradox here:
Not quite a paradox. The thread titles are inclusive of things which may fall into other categories, but can be posted in the general Tweets/Pictures/Videos threads by virtue of being interesting, funny, or random. The dilemma is where to post without violating the 12th Commandment of "Thou shalt not cross-post." Personally, I'd x-post with a disclaimer, and brace for the ire of the x-post police.
