why www? no www!
Ever heard a radio announcer read out a website address “double u double u double u dot sydney restaurants dot com dot au”. It really takes a very long time to say ‘www’. So why do it? Why do we put a ‘www’ on the front of a domain name if everyone has it? The time has come for web hosts and site owners to drop the ‘www’. By all means, still allow people to reach your site using ‘www’ but make the necessary changes to your server settings (.htaccess etc) and redirect the ‘www’ to the blank host record equivalent.
Read more about how to do it here: 
We can only leave the www (and the http:// for that matter) off because our browser compensates. If you were to just have server.com this is a different server location for a non-http protocol. So instead of getting rid of www, we should really be using http:// as well, irrespective of redirects - also you may end up confusing search engine spiders who can’t decide if http://example and http://www.example.com are the same thing or not. A domain is a domain.
