@rlamacraft I think it's because those platforms are depending on a certain kind of uniformity to be succesful. If I have to read a different font every time in the timeline, I'll go elsewhere where my sanity is not going to be tested to the limit. 😋
@rlamacraft Not all messaging platforms evolved from SMS though. Mastodon, for example. ;)
If you want real personalized messages, I guess html-email works. :P Or you can attach PDF documents with your stylized content, or even post an image of it. Granted, that's a bit cumbersome. But people do it, so...
