Definitely. At work today we were watching a video on Machine Learning by Andrew Ng and he made a number of references to LeCun's involvement the field, and listed him in the acknowledgements section of his talk. It has encouraged me to look into more of his areas of work.
I took the very first course when it was a Stanford experiment and I have to say that was a lot of fun! It feels a bit downgraded in terms of difficulty but quality wise was very good.
I signed up for Andrew's ML course (https://class.coursera.org/ml/lecture/preview , start date is not announced yet). Really looking forward to it.
