Interesting. Shaw specified that shavian alphabet should be a complete replacement to avoid the jarring appearance of misspelling though right? Porting those conventions into standard english orthography seems to violate that.
It's because language changes gradually over time. Most people who aren't English Majors or have a Linguistics degree don't even know what a Thorn is, and I don't even blame them. (Also the fact that no Middle English characters are on my keyboard, closest I have to a dead symbol is ‽)
Same, personally I find it quite hilarious ðat people bitch at me about how "th" is mandatory because linguistic development and ðen in ð same breaþ condemn ‽ as quirky bait.
I þink it's important we have some fun wiþ language. Using historic letters is fun! So is þe interrobang! Who cares about þe people bitching‽ Language development doesn't need to be homogenous
