Aaron when I followed these instructions, I got this:
![configure_your_account___gina_trapani_s_thinkup-2](https://f.cloud.github.com/assets/60632/1059951/a8e418e6-11a5-11e3-8433-70e9c7cd01ef.png)

Are you supposed to enable Google+ as well?

Also, I was confused about the line regarding the developer key. Under what circumstances will I need this key? Where do I add it? I see you added some information about it in the documentation. Can we link to the doc, or say something more explanatory here, like "Very active YouTube users might want to obtain a developer key, which will enable ThinkUp to get data faster. Learn more..." (with a link). 

What do you think?

I'm just testing/code-reviewing now, expect some more questions/feedback in the next couple of hours.
