On what planet is this postmodern?

Sounds like a dreadful idea in terms of maintenance.

Technically impressive, but almost anything by Paul Rand blows 95% of these away. Not much soul, joy or delight here.

It's the accusation and click-bait that people are annoyed it. Such an unnecessarily angry tone.

Yeah but then it wouldn't get half as much attention...

I'm intrigued that you say that. This is essentially a typography ebook, albeit a very pretty one, for 10-20x the price you would usually pay. For comparison, Matthew Butterick and Danny Truong offer similar resources using a donation only model (with suggested amounts of around $20).

I think there's a little bit of confusion on both sides. Having read through a lot of the original author's comments on the initial DN post I think a better title would have been, 'There is no grid... framework'.

It seems to me that he's not suggesting we ditch grids entirely in some post-modern David Carson style, rather that we should design a grid system as per the unique requirements of the project, instead of than jumping to a framework to solve our problem. So don't ditch grids, just be more conscious about them.

In my own work i've found that responsive design has really messed with my idea of grids in general and i'm still picking up the pieces of what the best approach might be, so I can certainly empathise with some of this.

Sadly the title in its current form is rather incendiary, and doesn't really reflect the message (as I interpret it) so I can understand how people have jumped to the obvious conclusion.

So meta. Much comment.
