To answer your question about words and comments, you can input a word or a simple concept like a person's name ex: "George Bush".
As for the API keys every user currently has access to the same information via their API key. You are correct about the security flaw in the javascript API key model, however since nobody uses this but me, I figured it's OK to let it slide for now and once I need to start scaling I can figure out something else. Right now I just want to get people interested and start playing around with it.
