Nice write-up. I also use 5 different photo-sharing/storage sites; the only difference being that instead of 500px I use SmugMug, which BTW does allow RAW files. Recently I’ve felt tempted to give 500px a try but as you’ve said, I’d probably have to drop one of the other services (Instagram maybe?) since 6 photo-sharing sites might be too much. Then again, my photos are definitely not the quality that you’d normally see at 500px, so I may have to stick to gool ol’ Flickr and the like. .
