I think the thing is that off-topic is for actually talking to each other, versus the fire-and-forget nature of the wibblier threads. I'm well aware that the acronym thread is amusing and requires some creativity, but in the end it's mostly just go in, post an acronym of your name, go back out. You don't need to relate to ANY of the other posts besides the first one, and in fact, most people don't. They can, but they rarely do.

Now, don't get me wrong, i'd be totally fine with a new Wibbles, i'm just saying i can see what the mods are on about. Yes, low-effort threads can be fun, but they might very quickly drown out all other activity if not regulated or at least condensed.
