The Picture Thread Rule (no more that two posts in a row without a topical picture) is abolished here.
There is now no rule on minimum picturality. As an aspirational goal, try not to starve picture threads with too much yap and no pictures. That would be dull. And dull is not funny, And not funny is not on Humor Forum topic.
Also note that text posts still have to be on thread subject, they have to be about the pictures for the thread.
