Thanks Michael! And yes, it would be great that Google can set a precedent with these de facto push messages. The biggest problem here is, besides privacy ethics, what does anyone consider to be useful. This is a very personal question. I like Google warned me about delays. Others could find this unhelpful. This would also mean Google would need to mine more and more (meta) data on a larger aggregate level in order to deliver these 'personal' experience. Something startups could help with!
