I fully agree it's great fun, and my own contribution to the playpit is 
<https://nxg.me.uk/dist/lx/>, which is a syntax intended to look like 
the 'sexp' syntax that various Lisps use, which is parseable into a SAX 
stream (so the consumer of that stream doesn't have to know that it 
didn't originate in pointy brackets).

When I was thinking about that, I was concerned with very markup-heavy 
'texts' (such as XSLT), as opposed to the more traditional use-case 
(which I think MinML is aimed at?) where there is more text than markup.

Also, I just find the homogeneity of sexps really pretty!

Indeed (though the ')))))' problem is a non-problem if you have anything 
resembling a lisp head on you, or if you're using a programmer's editor; 
I agree this isn't everyone).

I think this is the big/deep/core point.

I'd guess that lots of  people have favourite ways that the XML syntax 
is Annoying, but it's a very 'engineer's' solution, which isn't pretty, 
but which is stable because it's being pulled in so many different 
directions at once.  I suspect large chunks of the various constraints 
would have to change, before the solution space would change enough to 
make a radically different syntax something other than a minority taste.

Best wishes,

Norman
