"Web site: a group of World Wide Web pages usually containing hyperlinks to each other and made available online by an individual, company, educational institution, government, or organization"

Almost every white paper I know capitalises the word "Web", but LEO writes it with a small "w"; With the exception of "Web page".

Shouldn't it be:

"World Wide Web", and not "world wide web"
"Web", and not "web" (when referred to the Internet)
"Web site", and not "web site"
"Web server", and not "web server"
