My experience with Netflix's video quality has been pretty positive, so they seem to have been doing something right. I hope this predictive model will only improve things and won't deteriorate quality (consider they tuned for low false negatives quality shouldn't decline).

This is a nice write-up of the business case for data science. It would have been nice to have a follow up with the technical details - but maybe that's deemed proprietary?

My problem with Netflix is that I rarely find streaming films I would be interested in watching. It's so bad that I don't even bother looking there any longer, I'd rather just pay the $2.99 and rent a film I'd like to watch from Play or Amazon.
