Google Chrome finally removed “http://” from the start of every web address we type, Chrome will omit it by it self 
This step might have been taken to follow the Chrome principle of making things Simpler … but technically Dashing out the HTTP:// makes no improvement of any sort , as this is just a protocol and if no other protocol is defined by default http is used. Making the approach to simplicity, That is achieved 
But that about the WWW ? We all know its a sub-domain , and most of the people are in such a bad habit of typing this WWW that when ever they begin first thing they type is “WWW” not knowing its just a sub-domain and its not compulsory that this will also be there. Internet explorer has spoiled the habits of internet users by giving the short cut of entering “WWW.domain.COM” by pressing CTRL+ENTER  and i know know why they still have this shortcut …
Generally most of the sites use the same site content on domain.com and www.domain.com and redirect it to the domain which they using like typing www.drhack.net redirects to drhack.net as drhack.net is not using the subdomain WWW … I think Google Chrome  can roll out the WWW dashing option that will save millions of bytes per day while not sending “WWW” in every website request. As for the HTTP is makes thing simple and thats about all and yes when ever we visit a secure site the https:// is shown in blue colour
