The Naked Bike Ride earned me my first slapped hand from Flickr who took down a video I'd posted of people cycling by, despite me following the rules by marking it as potentially naughty, because of course we must think of all those children who use Flickr for looking for everyday people's bodies naked. All the photos I took seemed to survive. What was irritating though was about a month after I posted it Flickr sent me an email saying that they were taking down one of my images for breaching their guidelines but not identifying what it was. Not posting much nudity on my Flickr it only took me a few minutes by process of elimination to work out what it was, but if the complaint had been somewhat more insane then Flickr effectively make it impossible for the user to defend anything they post up, despite the fact the user owns the image.
Very good Serpentine Gallery pavilion this year, though they did make up for it by having a public sculpture nearby of one rock on top of another called, yes, 'One Rock on Top of Another'. Ah, bless the Serpentine Gallery. They are there, all year round, giving the public what the public expect modern art to be.
