Am a big fan of Google Reader and have subscribed to hundreds of RSS feeds. I love browsing through Flickr. I am addicted to it, especially to their explore section, where daily they come up with few hundred most interesting photos from flickr for that day.
So I wrote a PHP Script which generates an RSS feed of the 100 most interesting photos on Flickr's explore, every single day via a cron job which uses Flickr API and a bit of cUrl magic. A 100 photos are published to the RSS Feed, every-single-day. The explore positions vary through out the day, but only those that appear to the script when it runs are considered.
Every single day I go through those photos, I am left inspired and mesmerized. There are so many amazing photographers out there, that simply watching their work is a delight. It just makes my day. Here is the Feed URL for you to subscribe for your photography delight.
