If you use Netvibes as an RSS aggregator, here’s a page filled with street photography feeds. Photoblogs, photographers, flickr streams, news feeds and such. Freely modifiable, of course. My watchlist needn’t be yours, natch.
Not sure what happens when I update the page (if you’ll get the updates, too) but it seemed like a good thing to distribute/share. Pretty much “street only” with this page. Click the image below to set it up.
If you set it up and find it useful, give me a shout.
