after using it for a day or so i've gotta say that flickr uploader works brilliantly. i dragged and dropped from both iphoto and the finder effortlessly and it's very low fuss. there are still some bugs in the software [see: wonky uploading, frozen progress bars] and it'd be nice if i could specify all the settings for the photos before uploading them. but for beta software, it's still good.
also, i think it should be called "uploadr". i understand the branding thing, but i'm all about simplification. i think it comes from working on the mac for too long.
