Excellent...!! No words to appreciate how beautifully and succinctly you were able to communicate the power of NLTK in such a short time. I have seen quite a few other presentations but though they were all good, this one was the most effective. It immediately gives a sense of what NLTK is all about and while watching this, I was able to think a lot of use cases I can use NLTK for. Great job, once again...!! Manoj Joshi
