O’Reilly Radar > Flickr and Interestingness:
“So I needed some good pictures as visual bullets. I first went to Google image search, but while the photos were good, they were all somewhat ‘expected.’ After paging through the first four sets of results, still hadn’t found anything suitable. So I went over to flickr, set my search to ‘most interesting’ rather than most recent or most relevant, and soon had a fabulous selection of unusual photos of cathedrals.Google made a breakthrough in web search with its original idea of links as citations (i.e. PageRank), and they are still the undisputed leader in general web search, but they haven’t done as well in searching rich media. I think they have some things to learn from Flickr.”
I’ve moved to Flickr as the source of images almost exclusively. The quality is high, many are under Creative Commons (which is great for my typical uses), and I can usually find multiple “good things” straight away.
