Thanks for bringing this up, Jon
It does seem inevitable that the ‘catch-all’ website is on the way out - if for no other reason than that (this kind of) technology is changing so fast that nothing can last for very long (10-15 years) any more.
I’m not sure that it’s chiefly a question of how much content is made available on websites; but what kind of content… so interactive FB-like personal news and ‘discussion’ will surely gravitate to one type of delivery mechanism; commerce to another; pure information (weather, traffic, news) to another - and so on.
If so, where would that leave RW?
The trick would seem to be to ensure that content and platform/delivery mechanism - however counterintuitive and whatever the temptations - be decoupled; at least in terms of their underlying technology. And that the media be made as self-standing, independent and amenable of development as possible in whatever environments emerge.
So - Instagram is where folk go to compare and discuss images. Waze to ensure a smooth commute. Twitter to get realtime news etc. Multiply that concentration and ubiquity by 10: that could well be the world we’ll be living in by 2020.
