But at this point, it's pretty clear that most non-technical people prefer emails with fancy text and graphics.
Personally, I'm just glad that email is a flexible enough medium to allow that. It's better than the alternative, where people moved to some closed, proprietary protocol behind like 20 patents that allows the same thing.
Is there any other common way we communicate over screens (aside from http) that has had the staying power of email for the general public? I think that's a testament to the sheer flexibility of it. The ugliness that people have contorted email into is a badge of honor IMO
