You’re holding it (your email) wrong

I’ve changed all my native email apps to sort conversations “newest at the bottom,” like Gmail.

When I read an article on the Internet, or anywhere, I read it from top to bottom. Why, then, would you read a conversation thread from bottom to top? Is the UI optimized for reading while hanging upside down from the ceiling? That sounds like a 5% case to me at best. 🙂
