Top solutions to help new code golfers?

I really wanted to look at top solutions to see what I can do better next time, but it appears solutions aren't published for code golf. I got it down to 99 characters which is good for 173rd place right now, so I know there are at least 172 of you that can help me out. How can I do better?
