Has anyone heard of blipfoto?
It is an online community website where users document their daily lives with a single photo and some text. I was introduced to it by a friend and it is totally addictive, almost as much as GN!!
It was founded in 2004 and reaches half a million people each day, all over the world. There is a rumour of the company's collapse but I believe it is being saved by a takeover.
It is quite challenging to find a subject of interest to post each day, and is another source of time wasting to explore!! 
People eating and drinking on the go
To think that London, or anywhere else for that matter, does not belong to any one demographic
