 # Quote of the Week
 
-<!-- QOTW goes here -->
+> If you write a bug in your Rust program, Rust doesn’t blame you. Rust asks “how could the compiler have spotted that bug”. 
+
+– [Ian Jackson blogging about Rust](https://diziet.dreamwidth.org/19480.html)
+
+Despite a lack of suggestions, llogiq is quite pleased with his choice.
