One of my favorite photo pools on Flickr is the WOW! pool where only photos with a WOW! factor are supposed to be contributed. While that’s a fairly subjective thing (cats? please), there really are some gems. Some of the most impressive photos to me come from places I’ve never seen before, such as exotic beaches, hiking trails, and small cities around the world.
You can subscribe to a pool’s photos by adding the RSS feed URL found at the bottom of each pool’s page.
Cute kid photos are a really questionable submission, but flying kids have serious WOW! factor.
Another interesting feed is photos tagged with the term Minneapolis. Photos of cool stuff going on around town come directly to me in Bloglines through this feed. Cool stuff.
