Some features I would like to see (some maybe only for PRO accounts):
-native RAW/DNG Support and storage/backup-at least a white and a black skin, better would be an additional 1 or 2 gray skins, too-better integration (sync) in Lightroom/Aperture,etc. or alternatively a real desktop app to manage my files, not just an uploader-a complete overhaul of the user interface, making use of web 2.0 technologies like AJAX, etc.-custom resizing (option to add 1 or 2 user defined sizes to the ones defined by Flickr)-more liberal linking options-a more flexible API regarding EXIF, descriptions, etc.-a market place to sell photos,prints,etc.
This reply by Flickr/Yahoo shows clearly what is typical for most things coming from Yahoo after the original web directory - a total lack of visions and understanding of usability. Interstingly enough, they are only looking for engineers and programmers. As if the problems of Flickr had anything to do with a lack of programming or engineering talent. Actually their superb resizing engine prooves that their programmers are top notch. What they really need is a product manager with a clear vision of the future and a background from the photographic industry. I would hate to see Flickr become just another social picture sharing site - leave all the handy shooters to Facebook & Co. Instead they should focus on the serious photographer (professional or amateur) who is interested in presenting photographs, not snapshots.
