Trying to learn all the time.
I am the creator / developer of http://chessworldchampionshipdata.com/ which is in V2.0 right now. It's a data visualization application for the history of the world championship. It took me about 36 months to get to this point due to lack of time to work on it. I'm very proud of it and I hope you all find it enjoyable.
I'm actively blogging here on chess.com:
