I was delighted to see this on the front page. Letter forms fascinate me and I enjoy playful explorations of the topic. They sit neatly between formal and informal systems and shed light on human cognition.

I'm very glad you're not the gatekeeper of what's here and what isn't.

I'm very glad most of the HN content does indeed satisfy more narrow criteria than "it could be interesting to someone".

> "it could be interesting to someone".

Nobody is saying that. HN content typically caters to a prticular kind of geeky intellectual curiosity - that I think often has broader interests than you're giving it credit for.

As someone else pointed out this post would fit nicely into Douglas Hoftadter's Metamagical Themas - a book with impeccable geek credentials.
