Had a very busy time in London, working with some friends, and then going to the Geek Dinner and Photowalk on Friday night. Saw a bunch of friends there, including Robert and Maryam Scoble, Ian Forrester, and Hugh MacLeod - and got to know Mark Earls, who wrote the teriffic book Herd.

Here's some of my favorite pictures from the Photowalk we did on the south bank of the Thames in London.
