I decided to make this after seeing that wit.ai's official ruby client was only able to send messages to wit ai and get the json response back. I made an entire library to request things from wit.ai, create bots to respond to intents, ect.
I just created a GH pages site for wit_bot. You can view it here: <a href="http://bensites.com/wit_bot/" rel="nofollow">http://bensites.com/wit_bot/</a>. It might be nicer. Your choice :D
