The problem with dropbox is that they don't have a client for automating backups. That means everything I store there has been manually dragged into the dropbox folder (see NB). It would take me a long time before the number of files I needed to share online exceeded their free limit. NB: Truth be told, I run batch files via task scheduler for backing up certain folder to dropbox, but I doubt the typical consumer does.
