Just learning Ruby, Advice Welcome!

Hello all,

I just started learning Ruby and really love it. I just started posting
all my code samples on a website and just wanted to let the community
know. If you see any ways to improve my beginner code, I would love to
hear advice from people who have been there.

Also, I figured other people learning Ruby might like to see some very
simple exercises (from Learn to Program) solved to perhaps give them
other ideas on how a problem can be addressed.

Thanks for the great language and community!

Paul
