1. Nope, no infinite loops; it will not re-respond to something already responded to.

2. True and yes, there's some NLP user-friendliness baked in. It's case-insensitive, not whitespace sensitive, and it knows that "it's" == "it is". Give it a try?

My question would then be, what would be realistically considered useful to you? Obviously I'm no AI Ph.D claiming that it will pass the Turing test; but I just thought maybe something "good enough" will be helpful to at least a small subset of people. Saying "hello" is kinda pointless, but say if you got a lot of repeat questions over Twitter (because you're a business or something), this will help you auto respond to them.
