Why does the RSA have so many really interesting things happening at lunchtimes, when I can't quite get there in time? (I really shouldn't grumble - they have lots of evening things as well, and for the 'impact of the internet on the general election' one I was at last week they'd even moved the start time back to 6.30, which is much easier for me to make.)

Also, on a planning ahead note : Walk London's Spring into Summer events are this weekend - 22nd/23rd.
