@@ -89,7 +89,4 @@ A few exercises based on things I've encountered or had trouble with getting use
 
 * File issues for problems or suggestions!
 * Contribute more exercises! Anything that took you time to get used to, or that you had trouble with, or that deserves practice would be a good exercise!
-* Organize the exercises (by topic? progression of difficulty?)
-* Add some exercises that are "make the test pass" instead of "make this compile"
-* Write some hints or sample answers
-* Figure out a nice way to link the code directly into playpen
+* How could the process of doing these exercises work better? This is an open-ended question :) Are the playground links good enough? Are there ways that we could make going to the next exercise easier without forking the playgound??
