Short answer

I don’t know. I’m not exactly that great at the lateral thinking required to interpret symbolism and representations and deeper meanings. I’m not sure if he ever fielded a question about his choice of this symbol (or even whether his OC, Null, came before or after). It seems like the sort of question others before me may have thought about intensely and extensively. If such people want to send in their interpretations, the ask box is always open~ Personally, I’ve never dedicated that much time to considering this…before now…

Long answer

Well… What is the empty set? A collection of objects defined by its lacking of any objects at all. It is a collection with nothing in it, but it is still technically a collection, and it is the only such collection that exists. In a world of mathematics where virtually the only sets which are useful at all are ones with at least one object inside them, it is something of a paradox that a set with nothing inside it, but not in and of itself nothing, should exist at all. What does this make it? A peculiarity; an anomaly. Perhaps, some might even say, no more than a curiosity. It has almost no function, it simply is, but still we make admissions for it, we regularly acknowledge it, and sometimes, just sometimes, it even shows up for a reason

What is SoGreatandPowerful? Or rather who? In fact, I believe it is a question of “Who is SoGreatandPowerful, to SoGreatandPowerful?” By this point it has been made clear, countless times, that unfortunately he does not hold himself in high regard. He is harsh on both himself and his art, the latter especially in all its forms. But at the same time, I think he recognises that he is still doing what many others cannot. He may not necessarily place himself as better than certain other people, but perhaps he still realises he is unique. A peculiarity; an anomaly. Solely to himself, maybe no more than a curiosity. He has his adage: “what’s mine is yours. feel free to use anything you find here for whatever purpose you so desire. even giving credit is an excess.” A rogue function, spontaneously generating output with no care for whether anything else should receive it, and especially not what happens to it next. A sum body of work worth nothing at all. But it knows, he knows, he is not useless. And sometimes, just sometimes…he even feels he has a reason
