The @ is just a fancy a, so i don't think it's a good idea, generally i don't think it's a good idea to use any letter or symbol that doesn't match at all our languages, it just feel to forced and most of those "solutions" include a group but exclude another big group: people with dyslexia, but also those with dysorthographia at times;

My take is: we ditch one of the 2 genres and we have only one, or we add a thirdy one with a nicer sound than shit like -x, -ə or -u which is kinda hard tbh, maybe we can take a letter from some other alphabet?

One guy doing that bit is already too many

Lol I'm so glad this thing isn't catching on and is so often ridiculed by the people it's supposed to "help." I see that silly X and my phonetic brain just goes

"Lah-tinks" or in the above poster's instance "Fill-ih-pinks". LMAO wat? Who would appreciate that?!

This is the same culture-warrior neckbearding that wants to crusade and die on the hill that "Hey guys" should be offensive to anybody in a mixed group who doesn't just so happen to be male.

It feels like the kinda thing that only sounds like a good idea when people are so isolated they only communicate online.
