RE: Srikant/Hari,
Iv got no idea how successful photowalks have been in other cities, for Wikipedia Takes Mumbai 1 we had 4 of us (1 of the 4 being a visiting American Wikipedian). For the second, we dint seem to get a good response and it was delayed indefinitely. This is why I got thinking and came up with the Flickr alternative. In case we get a better response, yes Photowalks should continue.
Regards,
