Now that Flickr is getting very popular, it’s almost useless for getting photos from world events. Just a few months ago, getting a tag feed for some newsworthy current event returned pictures from people at the scene. The immediacy and the alternative to the wire services made it interesting.
Now everyone just uses Flickr as a generic photo hosting service and reposts wire service photos to reuse them on their blogs. It’s impossible to plow through all that noise to find the gems people are posting that you’ll never see on Yahoo! News Photos.
