Lots and lots of it:
1. Jan Chipchase on designing for social spaces.
2. Rory Sutherland on why advertising is actually democratic.
3. James Whatley on the hierarchy of communications, with an addendum from The Outsidr. (Interesting isn't it that despite all the advances in technology and communications we enjoy, it's still a personal touch - in terms of voice - that people will prioritise. At least for communications from people you know...)
All will give you much to chew over. Enjoy.
