 # Quote of the Week
 
-<!-- QOTW goes here -->
+> New users feel like iteration times are so slow and it takes forever to get going with Rust. But if there's a library available, I feel like I'm roughly as productive with Rust as I am with Ruby, if not more, when I think about the whole amount of work I'm doing. I haven't really figured out how to talk about that without sounding purely like a zealot, but yeah, I feel like Rust is actually very, very productive, even though many people don't see it that way initially.
