The most penetrating exhibit at the Stasi Museum in Leipzig isn't in a glass case. Housed in the 'Runde Ecke' ('round corner'), the nickname for the old Stasi HQ, the museum has sought to preserve the smell of the GDR. It's an antiseptic aroma, with a bleached ageing sweetness to it, as if you found a tube of Germolene from 1912. I don't know how you hang onto a smell, but they've kept the beige patterned lino, the metallic filing cabinets, the creamy grubby walls, so perhaps that's part of it. I wonder what they do if they sense the pong is fading.

The line that got the most applause at the opening rally of the Liberal Democrat conference in Glasgow came from Nick Clegg, but it wasn’t about housing or tax or civil liberties or nuclear power. It was about the party itself: ‘People who don’t understand us like to call debate division. I think it is debate that gives us our unity.’ He said that after the Syria vote he’d told David Cameron: ‘It’s not a defeat, it’s just a reference back.’

This was a big week for Facebook feminism. A worldwide coalition of feminist groups, led by the UK's Everyday Sexism Project and Women, Action and the Media in the US, have been challenging Facebook's advertisers (mostly via Twitter) to suspend their ads until the platform agrees to remove some straightforwardly offensive images making hitting and raping women sound like fun. (They are depressingly easy to find on the internet. A couple is having dinner, a single rose in a vase on the table: 'Win her over... with chloroform.' This is the tame end.) If asking the advertisers to ask Facebook to ask whoever posted the images to take them down sounds like a roundabout way of going about things, that's because it is: Facebook, who have censored photos of breastfeeding in the past, had already vetted the images and didn't think they violated 'Facebook's Community Standard'. On Wednesday they backed down and issued a statement setting out how they were going to change their moderators' ways.
