So you see this URL:

    vnoid.de/~user/stuffs

vnoid.de is shared by multiple users. What I do is: In case you wonder
how it works on the server side:

File System
-----------

/srv/userhome/      symlink
-------------       -------------------
├── user1           ->  /home/user1/www
├── user2           ->  /home/user2/www
├── user3           ->  /home/user3/www
└── user4           ->  /home/user4/www

Nginx
----------

server {
	server_name vnoid.de;

	location ~ ^/~(.+?)(/.*)?$ {
		alias /srv/userhome/$1/$2;
		index index.html index.htm;
		autoindex off;
	}

    // SNIP
}

The regex says: a url staring with vnoid.de/~xyz (note the tilde) will
use /srv/userhome/xyz  as document root.

For convience, the webroot is symlinked to /home/user/www
To synchronize the files:

rsync -e "ssh -q" -avh -og --chown=shrik3:http \
    --update --delete-after \
    path_to_my_blog_local/ shrik3@vnoid.de:~/www/
