My resolution: answer some questions on Stack Overflow
I can't count how many times I've pasted an error message into Google and arrived at Stack Overflow where some kind person has written a solution to the problem I'm having. It (and sites like it) have helped me gain an understanding of Ruby and helped me build all of the things I do in the language.
So - time to stop being a leech and start contributing. This year you'll find me answering questions about Ruby, Sinatra, maybe a bit of Rails, probably some jQuery, amongst other things.
There's a new stack overflow page on this site so you can all hold me to account if I don't do this :-)
