This isn’t a recommendation specifically related to my mission of finding great things to do in London.  But if you find yourself with some down time sitting in the sun drinking a frappucino with your ipad, i highly recommend the eclectic articles that can be found on the browser.   The Browser has been publishing daily since late 2008 and each day the editor  recommends 5-6 pieces of reading that he thinks are worth your valuable time, plus the occasional video and quotable quote.  I find that I get immersed in one article after another and this is problematic because it’s hard to get back to the piles of work on my desk.   Read it at your own risk!
