Have you come across http://www.stumbleupon.com You go to the site and checkmark all the subjects you are interested in and then install the “Stumble” button into your browser, Internet Explorer or Firefox and then when you are bored (like in work) you click on the stumble button and it throws back a random webpage to you based on your preferences. Any pages or sites that you come across you can mark with a thumbs up or a thumbs down. Then after a while based on your thumbs it fine tunes the kind of things you are interested in.
Its pretty cool and I have come across a load og photographers sites with some pretty cool, weird and interesting shots that I would otherwise have never seen.
