I think this is probably true to most people, and therefore good advice, but boy howdy do I still notice the repeats in e.g. "handwriting" fonts with extensive alternates -- the worse the quirkier the glyphs are supposed to be.
It's a free font, and I occasionally see it used in posters for rock shows or other "alternate" events.
But your point is right on. I only created three alternates per glyph, if I remember correctly, so if you were to try to use it for an entire page of text, it would reveal its tricks pretty quickly. For just a title or header, I think it holds up.
(Having said that, there's definitely a bit of craft, if not art, in choosing the right glyphs and getting the kerning right.)
