The day went by very fast. However not a lot of interesting topics though. The keynote talks by Ben Goldacre and Avinash Kaushik were all right. Then the Netflix one was interesting, the speaker talked about what (quite a lot of) other things Netflix does beyond predicting ratings. The 'science of data visualization' was informative too.
One interesting observation I made today was that during the break hour, the man's room had lines, while the ladies' did not. That's totally different from other places I have been to, for example, the shopping mall. :P
