Algorithm That Makes Preschoolers Obsessed with YouTube
This is how my 11 year old daughter uses YouTube now...  After 30 min, DNS no longer works for entertainment sites.  In order to fix that she has to do 5 Khan problems or read thoery.com, Duolingo, prodigy math, code monkey, splash math, Xtra math, or typing club.  It takes her 5 to 7 mins to earn points.  My server detects points and re enables DNS replies for YouTube, etc.  Best result so far is she now understands how fast 30 mins goes by and has no interest in watching YouTube all afternoon.  I have spent ton of time and resources on this last 12 months.  We are releasing new beta in 2 weeks.  DNSLearning.org.  Do Not Stop Learning.
