That's like saying that ever programmer in industry should spend 5-10 hours a week keeping up with the latest CS research on top of the work they put into their continuing education. It's just not reasonable to expect academics to know the latest JQuery or Enterprise Confabulator or whatever API. If you're doing CS education, you have a very small window of opportunity at the start of someone's career to teach them things that they're not necessarily going to pick up working in industry. You really need to think about what you can teach them that will allow them to be prepared for 30-40 year careers and whatever technological changes that brings.
