Somehow, HN seldom seems to grasp that people are inherently lazy and any solution that cuts work for them will find at least a few takers.
My mum can use Dropbox. She could not set up an ftp account, mount it locally with curlftpfs, and then use SVN or CVS with it.
I would dispute "inherently lazy" in favour of "have better things to spend their time on than crafting a personal solution to an already solved problem".
