What was intended to be a way to simply send messages back and forth and communicate like civilized humans; email has evolved into the centralized place where many people get actionable items.
MIME email includes a multipart/alternative header that allows you to send alternative versions of the same message; almost always to have an HTML and a Plain Text version of the same email; where the latter doesn’t have to be simply an HTML stripped version of the former.
To say the least, it is a brilliant idea. I can’t wait for the day where my email client is more than just a window to little pieces of notes—I want them to do something relevant depending on their individual context.
So obvious, and yet so far from reality.
