While I can certainly see why Deviant Art doesn't allowed multiple uploads or at least a faster process, it certainly turns me off from actually posting most of my creations here for lack of time...or maybe just utter laziness when I can simply upload them to photobucket.com to suit my needs rather than "show off" my work and label/tag and title everything that I post.
Still, Deviant Art is trying to be a serious art community and being treated like a simple image host would probably be bad for its image. I'll probably get around to posting some of my more recent, or better work when I feel like dealing with the bothersome process.
