How to Reach Me
If you want my advice or want to ask me about Data Science, please consider asking the question on Quora, and then sharing the question with me via an Ask-to-Answer Request, a Quora message, or an email. If you would like to become a data scientist, I would recommend you start with How to become a data scientist - Quora or the Quora Data Science FAQ.
I prefer answering questions publicly on Quora, since I get a lot of similar questions about Data Science, and Quora lets me write one really good answer that I can share widely. I can't guarantee that I will be able to answer all questions directed at me.
