When you see this prefix “http://,” you automatically know that it’s a web address, don’t you?!. So, since most web addresses are easily recognizable anyway, do we really need “http://” at the front of a web address?
The developers of Google Chrome also think that the “http://” prefix is not needed, so they simply chose to hide it in a developer version of Chrome browser, Mashable reports.
It’s an aesthetic improvement, however not necessarily a functional one. You can hide the “http://” in an url bar of browser, but it doesn’t mean it’s not really there. Some users — as seen from the comments from the Chromium wiki thread – have already reported the feature as a bug; others worry that it’ll train users to omit it, which could cause problems. More over, some software looks for the “http://” when auto-linking URLs.
One commenter said: “Many blogs, message boards, email viewing software, instant messaging software, etc. depend on matching against http:// to auto-link URLs. Removing http:// will train end-users to omit it, which will have a negative impact on usability all over the web.” [via Newser and Mashable]
