I'd love to move over to Picassa from Flickr, but the fact that every photo needs to be in an album is a deal breaker. I take one random photo and in order to upload it I need to put it in it's one, one-photo album? Or I can make a catch-all album that quickly becomes buried because it's my oldest? What a pain. If they just had some kind of "photo stream" I'd be all over it.
